University of Liverpool (United Kingdom)
|
The University of Liverpool is one of the UK's leading universities and plays a key role in
economic development in terms of employment, skills, research and technology. Currently the
University has over 19,000 registered students and an annual income of £219 million, which
includes £75 million for research.
The department of Electrical Engineering and Electronics is renowned for its excellence in
research and a rating of 5A was awarded to the department in the last assessment exercise.
The Solid State Electronics Research group operates in the new Wolfson and BioMEMS
laboratories, which are located in 800 sqm of mainly class-100 clean room environment. The
group focuses on the design, fabrication, testing, measurement, analysis and modelling of
micro/nano structures and devices that integrate silicon and related materials.
