Research on vapour growth of semiconductor compounds led to a key breakthrough in growing large crystals which form the basis for sensitive X-and gamma-ray detectors. The process was commercialised by a Durham University spin-out company, Kromek Ltd., which floated on AIM at £55M and has over 100 employees in the UK and USA. The X-ray detectors are in use in Kromek's security systems for screening liquids at airports, significantly reducing restrictions on duty free goods. This application won the $400,000 international prize in the 2009 Global Security Challenge. The company also markets gamma-ray detectors for nuclear isotope identification. These have won contracts totalling $7.5M from the US Defense Threat Reduction Agency and are in use at Fukushima.
Research on high-voltage power devices by the University of Cambridge Department of Engineering (DoEng) was commercialised by its spin-off company, Cambridge Semiconductor Limited (CamSemi), which, in the REF period, has:
CamSemi chips are more efficient than traditional linear power supplies. The CamSemi chips that were produced before the end of the REF period are estimated to save of the order of 100GWh of electricity and 50,000 tonnes of CO2 emissions per year in total.
Surrey Spin-out Surrey Nano Systems (SNS) is a business based around key patents resulting from the work of Prof. Ravi Silva and his team. SNS has raised over £11M from investors who have scrutinised the technology and recognise its value. The business develops technologies for low-substrate-temperature growth of carbon nanotubes (CNTs) and for novel low-k dielectric materials both of which align with the International Technology Roadmap for Semiconductors (ITRS). SNS is working closely with multinational leaders and has attracted a team that includes senior management experience of selling into the semiconductor process equipment market.
Nanomaterials research at Ulster into materials including diamond-like carbon (DLC) ultra-thin films, carbon nanotubes (CNT), graphene, silicon and metal oxide nanoparticles has resulted in direct uptake by major industrial manufacturers and led to a directly quantifiable socio-economic impact via added value, improved efficiencies and cost-savings and has secured or increased the employment of skilled engineering staff. Examples of this impact since 2008 include ceramic nanoparticles research in partnership with AVX Ltd that resulted in improved production efficiency processes (up 20%) and higher quality devices (up 10%). [text removed for publication] Research into ultra-thin DLC films, funded by Seagate, has led to their incorporation into magnetic media. [text removed for publication] Our nanoparticle research has attracted a new spin-in company SiSaf Ltd. (2009) and by incorporating NIBEC's expertise in nanomaterials into its business plan, the company was able to grow to a valuation of £3.5m and employ 7 people in skilled technical positions.
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.
Radiation sources and amplifiers, in the spectral region from microwave to terahertz, are extensively used in UK industry and public sectors such as security, defence, health and the environment. Companies, including e2v Technologies plc. (e2v) and TMD Technologies Ltd. (TMD), have developed and sold new radiation products based on post-1996 research undertaken at the University of Strathclyde. Their devices accessed new frequency ranges with considerable increases in power and bandwidth. The designs were transferred to industry, where devices have been constructed, jobs created, policy changed and considerable investments made. These sources have had extensive beneficial impact through applications in defence, surveillance, materials processing, health sciences and environmental monitoring.
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).
Viewing carbon nanotubes (CNTs) as very rigid polymer molecules led to research on turning them into useful materials. Strategic investments to develop different aspects of this research have been made by two separate companies. A process for the synthesis of CNTs was transferred to Thomas Swan Ltd who have made significant investment, and are now Europe's leading supplier of high-quality CNTs. In 2003 a process was invented to spin CNT fibres directly from a synthesis reactor. The process is intrinsically cheaper than the conventional process for carbon fibre and it produces a tougher and more versatile product. The University of Cambridge (UCAM) spin-out company Q-Flo Ltd (created in 2004 to achieve focus on transfer of this technology) and Plasan (multinational manufacturer of vehicle defensive armour) formed a joint venture in 2010 which has enabled the first-stage scale-up of manufacture.
Developing renewable sources of energy has to go hand in hand with reducing energy demand through increased energy awareness and behavioural change. To this end a multidisciplinary consortium of researchers, led by Professor Christopher Howe (Biochemistry), have developed several biophotovoltaic (BPV) devices for off-grid electricity generation, and as educational tools. This has resulted in impact on commerce (i.e. the acquisition of a BPV spinout company by Ortus Energy Ltd in 2009 through share exchange), on society and culture (an award-winning `Moss Table' developed by the consortium, which incorporates BPV technology, has been exhibited internationally since 2011 and has received extensive international media coverage) and on educational practices (a prototype BPV educational tool for schools has been developed by Howe and colleagues in 2013 and trialled with 6th form students).
Research at the University of Bath on highly structured materials for adsorbing and separating gases has created business and economic impact via:
