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.
Researchers within the Department of Physics and Astronomy at UCL have investigated the properties of defects in bulk HfO2 and at Si/SiOx/HfO2 interfaces. Results have been used by an industrial partner, SEMATECH (SMT), to improve the quality and reliability of high-performance microelectronic devices based on transistors. This has helped SMT to meet project objectives on behalf of member companies such as Intel and IBM, and UCL research results have been consistently highly evaluated by these companies. Recommendations made by SMT have been implemented by industrial partners in their currently manufactured devices, such as the 22nm process technology released by Intel in 2011.
A device developed for spintronics research at the University of Oxford has been adapted as the basis for robust, high-performance position or composition sensors to detect many different materials including metals, plastics, ceramics and fluids. These sensors are capable of making contactless measurements in very hostile environments. A spin-out company was formed in 2004 to exploit and apply this technology to a wide range of technical and engineering problems and has achieved over £2.5m revenue. These sensors form the key elements of products that have been successfully deployed in automotive and other transport applications. Benefits to end users include ease of use, speed and the cost savings.
The development of unique computer simulation tools has profoundly influenced the design and manufacture of silicon chips fuelling the $300 billion per year semiconductor industry. A pioneer of statistical variability research, Professor Asen Asenov developed understanding and awareness of statistical variability in the nanoscale transistors which make up all silicon chips. Gold Standard Simulations (GSS) was created in 2010 and by 2012-13 had grown revenue from services and licensing to $1million. GSS tools are currently used in foundries providing 75% of all semiconductor production for fabless design companies globally. For example, working with GSS and their simulation tools has reduced the development time for IBM's next generation of CMOS technology by 1 year, representing significant savings in the 3-5 year technology development cycle.
The isolation and characterisation of graphene by Geim and Novoselov demonstrated its potential to underpin disruptive technological change across an incredibly broad range of industries. This resulted in rapid global uptake of new technologies in the REF period, with at least $200m recent commercial investment in graphene production. Blue-chip companies have also made significant investments leading to the generation of 7740 industrial patents. The first set of graphene-based products has reached the market with revenues already exceeding $10m per month. This commercial activity has been matched by global shifts in public research and innovation funding of at least $2.4bn, as governments have moved to facilitate graphene research and commercialisation.
