Durham researcher, Prof Stewart Clark, is one of the six original co-developers of the Castep software package which calculates the electronic, physical and chemical properties of materials from first principles. Castep was written to solve a variety of research problems from semiconductor devices and liquid crystal displays, to the behaviour of Earth minerals under very high pressure, molecular dynamics and biological systems. The software package was commercialised for use in industry under license by Accelrys Inc., where it is bought and used by ~1000 high-tech companies for development of new materials in chemical, pharmaceutical, auto and jet engine manufacturing industries. Total sales revenue for Accelerys from the Castep code is in excess of $30M.
The development of Molecular Beam Epitaxial (MBE) growth techniques for self-assembled quantum dots at Cambridge University has led to the creation of electrically driven, compact single-photon and entangled-photon sources, and their demonstration in quantum key distribution (QKD) systems. This highly-cited work has led to significant recent investment in R&D in this area by Toshiba, one of the world's leading microelectronics companies, influencing company policy to the highest levels. It has stimulated world-wide interest in quantum information technology, in government institutions and companies from start-ups and SMEs to multinationals.
Our research on semiconductor materials and devices has led to the establishment by e2v Technologies of a combined manufacturing, research and development facility within the School of Physics and Astronomy. We have adapted and transferred device simulation software to e2v, and have provided epitaxially-grown semiconductors and access to fabrication facilities which have been used in their manufacturing processes. Devices fabricated within the facility, which was opened in 2011, have generated sales of £7M for e2v. This initiative has also led to shifts in the investment priorities of e2v, and mitigated risks to the company arising from import restrictions associated with the US International Traffic in Arms Regulations (ITAR).
Research at the University of Cambridge, Department of Physics on sensitive techniques for measurements of magnetic and electrical properties of materials led to the selection of Dr Michael Sutherland as an expert witness in a series of major police investigations involving fraudulent bomb detecting equipment. Scientific evidence Dr Sutherland presented in court was key in securing guilty verdicts, leading to the breakup in 2013 of several international fraud rings with combined revenue in excess of £70 million. This criminal activity had caused significant damage to the reputation of the UK in Iraq and elsewhere.
Research in the Microelectronics Group of the Cavendish Laboratory in the area of single-electron nanoelectronics, quantum computing and spintronics has been exploited by Hitachi, one of world's leading microelectronics companies. Research breakthroughs made in the Cavendish have defined Hitachi's R&D directions in quantum computing and spintronics, led to several Hitachi product developments and influenced senior Hitachi strategic decision makers regarding the future of computing.
The research on the use of single source precursors in quantum dot synthesis undertaken by Professor Paul O'Brien in the Department of Chemistry at Imperial College between 1994 and 1999 resulted in papers and a patent which led to the formation of Nanoco Group PLC, currently a world-leader in the supply of quantum dots (QDs). Quantum dots have applications in backlighting for LCD displays, LED general lighting and thin film solar cells. Nanoco was listed on AIM on the London Stock Exchange in 2009 and by January 2013 Nanoco employed 78 people, had annual revenue of £3 million, and had signed agreements with several major companies in the US and Japan including Dow Chemical, Osram and Tokyo Electron.
The research underpinning Stephen Hawking's books, TV appearances and lectures has shaped public attitudes towards frontier research in cosmology. It attracts large audiences to learn about his research, and he is the most well-known scientist in the world. Highlights include the publication of his 2010 popular-science book The Grand Design, and the Discovery Channel series Into the Universe with Stephen Hawking. Further evidence of the impact of Hawking's research was the award of the 2009 Presidential Medal of Freedom (America's highest civilian honour) and his role as narrator in the 2012 Paralympic Opening Ceremony watched by over 11M UK viewers.
Research undertaken in the University of Cambridge Department of Physics has provided benchmark data on, and fundamental physical insights into, the high strain-rate response of materials, including powdered reactive metal compositions. The data have been used widely by QinetiQ plc. to support numerical modelling and product development in important industrial and defence applications. One outcome has been the development of a reactive metal perforator for the oil industry which significantly outperforms conventional devices. These devices `perforate' the region around a bore-hole, thereby substantially enhancing recovery, particularly in more difficult oil fields, and extending their economic viability. Over a million perforators have been deployed since their introduction in 2007.
