Dr. Silva's research interests are in the characterization, growth and processing of novel semiconductor materials for large area electronic applications.

Ravi Silva is the Professor of Solid State Electronics and Head of Large Area Electronics at the School of Electronics, Computing and Mathematics. He was the Undergraduate Admissions Tutor for Electronic Engineering until Sept. 2001. He joined the University of Surrey in 1995 as Lecturer in Large Area Electronics. He did his undergraduate and postgraduate degrees at the Engineering Department at Cambridge University. After which he stayed on for a further year and a half as a Research Associate also at Cambridge prior to joining the EE department at Surrey.

His PhD thesis at the Engineering Department in Cambridge showed that Quantum size effects were observed in Amorphous band gap modulated Superlattice structures using a single elemental system, namely amorphous carbon. The variation in the band gap obtained by varying the relative percentage of pi to sigma bonds within the film.

Prof. Silva has research experience in the areas of amorphous films, displays, semiconductor devices, solar cells, large area electronics, fullerenes, etching and plasma physics and vacuum equipment gained over 12 years. He is responsible for publishing internationally some of the first work on band-gap modulated superlattice structures using a single homogeneous material system (a-C:H) that shows quantum size effects, some of the first work that showed evidence of electronic doping of plasma deposited amorphous carbon thin films as well as reporting of field emission from amorphous carbon and amorphous silicon films at low electric fields. He has a joint worldwide patent on field emission devices based on amorphous Si backed by Philips. Recent patents include the growth of carbon nanotubes, nanofibres and carbon nanoropes at low temperatures. He has published over 100 papers in refereed journals and over 140 papers presented at International conferences. He has conducted research at both the University of Kaiserslautern in Germany and Nanyang Technological University in Singapore. He has been successful in obtaining research funding in excess of £1.8M from EPSRC, industry and the Royal Society.

Prof. Silva is a member of the Advisory panel for the National Centre for Excellence in Si Microelectronics (NESM) and is a co-applicant of the successful bid for £10M to set up an Advanced Technology Institute at the University of Surrey. This building will be ready for habitation in May/June 2002, when his group will move to their new premises with bespoke laboratories.
He was awarded one of ten Outstanding Young Researcher Awards at IUMRS (International Union of Material Research Societies), Beijing, China, in June 1999, a conference that attracted over 2000 delegates.

In 2002 he was awarded the Charles Vernon Boys Silver Medal and Prize by the Institute of Physics for his 'outstanding contribution to experimental physics of electronic materials for advanced device applications, particularly in carbon based electronics'.
