Spinning, twisted light could power next-generation electronics

sc604 — Thu, 13 Mar 2025 18:09:28 +0000

̽��ֱ��researchers, led by the ̽��ֱ�� of Cambridge and the Eindhoven ̽��ֱ�� of Technology, have created an organic semiconductor that forces electrons to move in a spiral pattern, which could improve the efficiency of OLED displays in television and smartphone screens, or power next-generation computing technologies such as spintronics and quantum computing.

̽��ֱ��semiconductor they developed emits circularly polarised light—meaning the light carries information about the ‘handedness’ of electrons. ̽��ֱ��internal structure of most inorganic semiconductors, like silicon, is symmetrical, meaning electrons move through them without any preferred direction.

However, in nature, molecules often have a chiral (left- or right-handed) structure: like human hands, chiral molecules are mirror images of one another. Chirality plays an important role in biological processes like DNA formation, but it is a difficult phenomenon to harness and control in electronics.

But by using molecular design tricks inspired by nature, the researchers created a chiral semiconductor by nudging stacks of semiconducting molecules to form ordered right-handed or left-handed spiral columns. Their results are reported in the journal Science.

One promising application for chiral semiconductors is in display technology. Current displays often waste a significant amount of energy due to the way screens filter light. ̽��ֱ��chiral semiconductor developed by the researchers naturally emits light in a way that could reduce these losses, making screens brighter and more energy-efficient.

“When I started working with organic semiconductors, many people doubted their potential, but now they dominate display technology,” said Professor Sir Richard Friend from Cambridge’s Cavendish Laboratory, who co-led the research. “Unlike rigid inorganic semiconductors, molecular materials offer incredible flexibility—allowing us to design entirely new structures, like chiral LEDs. It’s like working with a Lego set with every kind of shape you can imagine, rather than just rectangular bricks.”

̽��ֱ��semiconductor is based on a material called triazatruxene (TAT) that self-assembles into a helical stack, allowing electrons to spiral along its structure, like the thread of a screw.

“When excited by blue or ultraviolet light, self-assembled TAT emits bright green light with strong circular polarisation—an effect that has been difficult to achieve in semiconductors until now,” said co-first author Marco Preuss, from the Eindhoven ̽��ֱ�� of Technology. “ ̽��ֱ��structure of TAT allows electrons to move efficiently while affecting how light is emitted.”

By modifying OLED fabrication techniques, the researchers successfully incorporated TAT into working circularly polarised OLEDs (CP-OLEDs). These devices showed record-breaking efficiency, brightness, and polarisation levels, making them the best of their kind.

“We’ve essentially reworked the standard recipe for making OLEDs like we have in our smartphones, allowing us to trap a chiral structure within a stable, non-crystallising matrix,” said co-first author Rituparno Chowdhury, from Cambridge’s Cavendish Laboratory. “This provides a practical way to create circularly polarised LEDs, something that has long eluded the field.”

̽��ֱ��work is part of a decades-long collaboration between Friend’s research group and the group of Professor Bert Meijer from the Eindhoven ̽��ֱ�� of Technology. “This is a real breakthrough in making a chiral semiconductor,” said Meijer. “By carefully designing the molecular structure, we’ve coupled the chirality of the structure to the motion of the electrons and that’s never been done at this level before.”

̽��ֱ��chiral semiconductors represent a step forward in the world of organic semiconductors, which now support an industry worth over $60 billion (about £45 billion). Beyond displays, this development also has implications for quantum computing and spintronics—a field of research that uses the spin, or inherent angular momentum, of electrons to store and process information, potentially leading to faster and more secure computing systems.

Switching ‘spin’ on and off (and up and down) in quantum materials at room temperature

sc604 — Wed, 16 Aug 2023 15:00:00 +0000

Spin is the term for the intrinsic angular momentum of electrons, which is referred to as up or down. Using the up/down spin states of electrons instead of the 0 and 1 in conventional computer logic could transform the way in which computers process information. And sensors based on quantum principles could vastly improve our abilities to measure and study the world around us.

An international team of researchers, led by the ̽��ֱ�� of Cambridge, has found a way to use particles of light as a ‘switch’ that can connect and control the spin of electrons, making them behave like tiny magnets that could be used for quantum applications.

̽��ֱ��researchers designed modular molecular units connected by tiny ‘bridges’. Shining a light on these bridges allowed electrons on opposite ends of the structure to connect to each other by aligning their spin states. Even after the bridge was removed, the electrons stayed connected through their aligned spins.

This level of control over quantum properties can normally only be achieved at ultra-low temperatures. However, the Cambridge-led team has been able to control the quantum behaviour of these materials at room temperature, which opens up a new world of potential quantum applications by reliably coupling spins to photons. ̽��ֱ��results are reported in the journal Nature.

Almost all types of quantum technology – based on the strange behaviour of particles at the subatomic level – involve spin. As they move, electrons usually form stable pairs, with one electron spin up and one spin down. However, it is possible to make molecules with unpaired electrons, called radicals. Most radicals are very reactive, but with careful design of the molecule, they can be made chemically stable.

“These unpaired spins change the rules for what happens when a photon is absorbed and electrons are moved up to a higher energy level,” said first author Sebastian Gorgon, from Cambridge’s Cavendish Laboratory. “We’ve been working with systems where there is one net spin, which makes them good for light emission and making LEDs.”

Gorgon is a member of Professor Sir Richard Friend’s research group, where they have been studying radicals in organic semiconductors for light generation, and identified a stable and bright family of materials a few years ago. These materials can beat the best conventional OLEDs for red light generation.

“Using tricks developed by different fields was important,” said Dr Emrys Evans from Swansea ̽��ֱ��, who co-led the research. “ ̽��ֱ��team has significant expertise from a number of areas in physics and chemistry, such as the spin properties of electrons and how to make organic semiconductors work in LEDs. This was critical for knowing how to prepare and study these molecules in the solid state, enabling our demonstration of quantum effects at room temperature.”

Organic semiconductors are the current state-of-the-art for lighting and commercial displays, and they could be a more sustainable alternative to silicon for solar cells. However, they have not yet been widely studied for quantum applications, such as quantum computing or quantum sensing.

“We’ve now taken the next big step and linked the optical and magnetic properties of radicals in an organic semiconductor,” said Gorgon. “These new materials hold great promise for completely new applications, since we’ve been able to remove the need for ultra-cold temperatures.”

“Knowing what electron spins are doing, let alone controlling them, is not straightforward, especially at room temperature,” said Friend, who co-led the research. “But if we can control the spins, we can build some interesting and useful quantum objects.”

̽��ֱ��researchers designed a new family of materials by first determining how they wanted the electron spins to behave. Using this bottom-up approach, they were able to control the properties of the end material by using a building block method and changing the ‘bridges’ between different modules of the molecule. These bridges were made of anthracene, a type of hydrocarbon.

For their ‘mix-and-match’ molecules, the researchers attached a bright light-emitting radical to an anthracene molecule. After a photon of light is absorbed by the radical, the excitation spreads out onto the neighbouring anthracene, causing three electrons to start spinning in the same way. When a further radical group is attached to the other side of the anthracene molecules, its electron is also coupled, bringing four electrons to spin in the same direction.

“In this example, we can switch on the interaction between two electrons on opposite ends of the molecule by aligning electron spins on the bridge absorbing a photon of light,” said Gorgon. “After relaxing back, the distant electrons remember they were together even after the bridge is gone.

“In these materials we’ve designed, absorbing a photon is like turning a switch on. ̽��ֱ��fact that we can start to control these quantum objects by reliably coupling spins at room temperature could open up far more flexibility in the world of quantum technologies. There’s a huge potential here to go in lots of new directions.”

“People have spent years trying to get spins to reliably talk to each other, but by starting instead with what we want the spins to do and then the chemists can design a molecule around that, we’ve been able to get the spins to align,” said Friend. “It’s like we’ve hit the Goldilocks zone where we can tune the spin coupling between the building blocks of extended molecules.”

̽��ֱ��advance was made possible through a large international collaboration – the materials were made in China, experiments were done in Cambridge, Oxford and Germany, and theory work was done in Belgium and Spain.

̽��ֱ��research was supported in part by the European Research Council, the European Union, the Engineering and Physical Sciences Research Council (EPSRC), part of UK Research and Innovation (UKRI), and the Royal Society. Richard Friend is a Fellow of St John’s College, Cambridge.

Researchers identify and clear efficiency hurdle for organic solar cells

sc604 — Wed, 29 Sep 2021 15:00:00 +0000

̽��ֱ��researchers, led by the ̽��ֱ�� of Cambridge, identified a loss pathway in organic solar cells which makes them less efficient than silicon-based cells at converting sunlight into electricity. In addition, they identified a way to suppress this pathway by manipulating molecules inside the solar cell to prevent the loss of electrical current through an undesirable state, known as a triplet exciton.

Their results, reported in the journal Nature, suggest that it could be possible for organic solar cells to compete more closely with silicon-based cells for efficiency.

Organic solar cells, which are flexible, semi-transparent, and cheap, can greatly expand the range of applications for solar technology. They could be wrapped around the exteriors of buildings and can be used for the efficient recycling of the energy used for indoor lighting, neither of which are possible with conventional silicon panels. They are also far more environmentally friendly to produce.

“Organic solar cells can do lots of things that inorganic solar cells can’t, but their commercial development has plateaued in recent years, in part due to their inferior efficiency,” said Dr Alexander Gillett from Cambridge’s Cavendish Laboratory, the paper’s first author. “A typical silicon-based solar cell can reach efficiencies as high as 20 to 25%, while organic solar cells can reach efficiencies of around 19% under laboratory conditions, and real-world efficiencies of about 10 to 12%.”

Organic solar cells generate electricity by loosely mimicking the natural process of photosynthesis in plants, except they ultimately use the energy of the sun to create electricity rather than convert carbon dioxide and water into glucose. When a light particle, or photon, hits a solar cell, an electron is excited by the light and leaves behind a ‘hole’ in the material’s electronic structure. ̽��ֱ��combination of this excited electron and hole is known as an exciton. If the mutual attraction between the negatively charged electron and the positively charged hole in the exciton, akin to the attraction between the positive and negative poles of a magnet, can be overcome, it is possible to harvest these electrons and holes as an electrical current.

However, electrons in solar cells can be lost through a process called recombination, where electrons lose their energy - or excitation state - and fall back into the empty ‘hole’ state. As there is a stronger attraction between the electron and hole in carbon-based materials than in silicon, organic solar cells are more prone to recombination, which in turn affects their efficiency. This necessitates the use of two components to stop the electron and hole from recombining rapidly: an electron ‘donor’ material and an electron ‘acceptor’ material.

Using a combination of spectroscopy and computer modelling, the researchers were able to track the mechanisms at work in organic solar cells, from the absorption of photons to recombination. They found that a key loss mechanism in organic solar cells is caused by recombination to a particular type of exciton, known as a triplet exciton.

In organic solar cells, triplet excitons present a difficult problem to overcome, as it is energetically favourable for them to form from the electrons and holes. ̽��ֱ��researchers found that by engineering strong molecular interactions between the electron donor and electron acceptor materials, it is possible to keep the electron and hole further apart, preventing recombination into triplet excitons from occurring.

Computational modelling suggests that by tuning the components of the organic solar cells in this way, the timescales of recombination to these triplet exciton states could be reduced by an order of magnitude, allowing for more efficient solar cell operation.

“ ̽��ֱ��fact that we can use the interactions between components in a solar cell to turn off the triplet exciton loss pathway was really surprising,” said Gillett. “Our method shows how you can manipulate molecules to stop recombination from happening.”

“Now, synthetic chemists can design the next generation of donor and acceptor materials with strong molecular interactions to suppress this loss pathway,” said co-author Dr Thuc-Quyen Nguyen from the ̽��ֱ�� of California, Santa Barbara, USA. “ ̽��ֱ��work shows the path forward to achieve higher device efficiency.”

̽��ֱ��researchers say their method provides a clear strategy to achieve organic solar cells with efficiencies of 20% or more by stopping recombination into triplet exciton states. As part of their study, the authors were also able to provide design rules for the electron donor and electron acceptor materials to achieve this aim. They believe that these guidelines will allow chemistry groups to design new materials which block recombination into triplet excitons, enabling organic solar cells with efficiencies closer to silicon to be realised.

Twelve Cambridge researchers awarded European Research Council funding

sc604 — Thu, 22 Apr 2021 10:00:00 +0000

Two hundred and nine senior scientists from across Europe were awarded grants in today’s announcement, representing a total of €507 million in research funding. ̽��ֱ��UK has 51 grantees in this year’s funding round, the most of any ERC participating country.

ERC grants are awarded through open competition to projects headed by starting and established researchers, irrespective of their origins, who are working or moving to work in Europe. ̽��ֱ��sole criterion for selection is scientific excellence. ERC Advanced Grants are designed to support excellent scientists in any field with a recognised track record of research achievements in the last ten years. Apart from strengthening Europe’s knowledge base, the new research projects will also lead to the creation of some 1,900 new jobs for post-doctoral fellows, PhD students and other research staff.

Professor Melinda Duer from the Yusuf Hamied Department of Chemistry has been awarded a grant for her EXTREME project to explore the chemistry that happens when a biological tissue stretches or breaks.

So-called mechanochemistry leads to molecules being generated within the tissue that may be involved in communicating tissue damage to cells. Detecting and understanding this chemistry is highly relevant for understanding ageing, and for developing new therapeutics for degenerative diseases and cancer.

“This award means I can do the research I’ve been dreaming about for the last ten years,” said Duer. “I am extremely grateful to the European Research Council for giving me this amazing opportunity. ̽��ֱ��ERC is one of the few organisations that understands the need for longer-term funding for high-risk, high-reward research, which is essential for this project. I really couldn’t be more delighted and I can’t wait to get started!”

Professor Manish Chhowalla, from the Department of Materials Science and Metallurgy, received funding for his 2D-LOTTO project, for the development of energy-efficient electronics.

“This grant will enable our research group to realise the next generation of energy-efficient electronics based on two-dimensional semiconductors,” he said. “ ̽��ֱ��funding will also support a team of students, early career researchers and senior academics to address the challenges of demonstrating practical tunnel field effect transistors.”

Professor Henning Sirringhaus from the Cavendish Laboratory received funding for his NANO-DECTET project, for the development of next-generation energy materials. “Worldwide, only about a third of primary energy is converted into useful energy services: the other two thirds are wasted as heat in the various industrial, transportation, residential energy conversion and electricity generation processes,” said Sirringhaus. “Given the urgent need to mitigate the dangerous consequences of climate change, a waste of energy on this scale needs to be addressed immediately.

“Thermoelectric waste-heat-to-electricity conversion could offer a potential solution, but the performance of thermoelectric materials is currently insufficient. In this project we will use the unique physics of molecular organic semiconductors, as well as hybrid organic-inorganic semiconductors, to make efficient, low-temperature thermoelectric materials.”

Professor Marcos Martinon-Torres from the Department of Archaeology received funding for his REVERSEACTION project, which will study how societies in the past cooperated. “Many prehistoric societies did pretty well at maintaining rich and complex lives without the need for permanent power hierarchies and coercive authorities,” he said. “Arguably, they chose to cooperate, and not just to ensure survival. ̽��ֱ��lack of state structures did not stop them from developing and sustaining complex technologies, making extraordinary artefacts that required exotic materials, challenging skills and labour arrangements. I’m keen to understand why, but also how they managed.

“This grant couldn’t have come at a better time, as collective action is increasingly recognised as the only way to tackle some of our greatest global concerns, and there is value in studying how people collaborated in the past. With our labs freshly revamped through our recent AHRC infrastructure grant, we are ready to take on a new large-scale, challenging archaeological science project.”

Professor Marta Mirazon Lahr, also from the Department of Archaeology, was awarded funding for her NGIPALAJEM project, which will bring a new understanding of how the evolution of our species is part of a broader and longer African evolutionary landscape.

“My research is in human evolution, a field that advances through technical breakthroughs, new ideas, and critically, new fossils,” said Lahr. “A big part of my work is to find new hominin fossils in Africa, which requires not only supportive local communities and institutions, but long-term planning and implementation, a dedicated team, significant funds and the time to excavate, study, compare and interpret new discoveries. This new grant from the ERC gives me all this and more – and I just can’t wait to get started!”

Professor Richard Samworth’s RobustStats project will develop robust statistical methodology and theory for large-scale data. “Large-scale data are usually messy: they may be collected under different conditions, and data may be missing or corrupted, which makes it difficult to draw reliable conclusions,” said Samworth, from the Department of Pure Mathematics and Mathematical Statistics. “This grant will allow me to focus my time on developing robust statistical methodology and theory to address these challenges. Equally importantly, I will be able to build a group of PhD students and post-docs that will dramatically increase the scale and scope of what we are able to achieve.

Professor Zoran Hadzibabic from the Cavendish Laboratory was awarded funding for his UNIFLAT project. One of the great successes of the last-century physics was recognising that complex and seemingly disparate systems are fundamentally alike. This allowed the classification of the equilibrium states of matter into classes based on their basic properties. At the heart of this classification is the universal collective behaviour, insensitive to the microscopic details, displayed by systems close to phase transitions.

A grand challenge for modern physics is to achieve such a feat for the far richer world of the nonequilibrium collective phenomena. “Our ambition is to make a leading contribution to this worldwide effort, through a series of coordinated experiments on homogeneous atomic gases in two-dimensional (2D) geometry,” said Hadzibabic. “Specifically, we will study in parallel three problems – the dynamics of the topological Berezinskii-Kosterlitz-Thouless phase transition, turbulence in driven systems, and the universal spatiotemporal scaling behaviour in isolated quantum systems far from equilibrium. Each of these topics is fascinating and of fundamental importance in its own right, but beyond that we will experimentally establish an emerging picture that connects them.”

Dr Helen Williams from the Department of Earth Sciences said: “By funding the EarthMelt project, the ERC has given me the amazing opportunity to study the early evolution of the Earth and its transition from a largely molten state to the habitable planet we know today. This funding will also help me to develop exciting new instrumentation and analytical techniques, and, most importantly, mentor and support the next generation of PhD students and postdoctoral researchers working in geochemistry.”

Professor Sir Richard Friend from the Cavendish Laboratory has been awarded funding for his Spin Control in Radical Semiconductors (SCORS) project, which will explore the electronic properties of organic semiconductors that have an unpaired electron to give net magnetic spin. ̽��ֱ��project is based on a recent discovery that this unpaired electron can couple strongly to light, allowing very efficient luminescence in LEDs. Friend’s group will explore new combinations of optical excited states with magnetic spin states. This will allow new designs for LEDs and solar cells, and opportunities to control the ground state spin polarisation in spintronic devices.

Professor Christopher Hunter’s InfoMols project is focused on synthetic information molecules. “ ̽��ֱ��aim of our project is replication and evolution with artificial polymers,” said Hunter, from the Yusuf Hamied Department of Chemistry. “ ̽��ֱ��timeframe for achieving such a breakthrough is unpredictable, and it is the flexibility provided by an ERC award that makes tackling such challenging targets possible.”

Professor Mark Gross from the Department of Pure Mathematics and Mathematical Statistics received funding for his Mirror symmetry in Algebraic Geometry (MSAG) project, and Professor Geoffrey Khan from the Faculty of Asian and Middle Eastern Studies was awarded funding for ALHOME: Echoes of Vanishing Voices in the Mountains: A Linguistic History of Minorities in the Near East.

Twelve ̽��ֱ�� of Cambridge researchers have won advanced grants from the European Research Council (ERC), Europe’s premier research funding body. Their work is set to provide new insights into many subjects, such as how to deal with vast scales of data in a statistically robust way, the development of energy-efficient materials for a zero-carbon world, and the development of new treatments for degenerative disease and cancer. Cambridge has the most grant winners of any UK institution, and the second-most winners overall.
