Electronic Materials and Devices

The Optical and Semiconductor Devices group was founded within the Department of Electrical and Electronic Engineering. Its research interests are broad and multi-disciplinary. Much of our work is concerned with the development of micro-electro-mechanical systems (MEMS), optical devices, low-power and microwave devices, and energy harvesting systems. Recently, we have conducted research in materials technology and device physics. A number of our projects are with industrial partners and many have an international flavour with particularly good links with our European and Japanese collaborators.

Optical and semiconductor devices are enormously important to today’s information society, making possible the gathering, storage, display, processing and transmission of data. The aim of the Group’s research is to develop new technologies that enable advances in materials, processes and device physics to be made. How can micro-texturing be used to build composite materials with new properties? How does a new class of semiconductor-based on organic materials work? How can optical gain be achieved within the dimensions of a small integrated circuit? How can the speed barriers of silicon microelectronics be exceeded? How can you build a small three-dimensional structure you can’t touch? How can micro-engineered devices help computers understand and control the local environment? Successful answers to questions of this nature will result in important new devices for the twenty-first century.
