Abstracts are not currently available in GtR for all funded research. This is normally because the abstract was not required at the time of proposal submission, but may be because it included sensitive information such as personal details.

Description | The continuity of funding has enabled us to make significant advances in the following areas: 1. Understanding of the reduction in efficiency of GaN based LEDs at high drive currents. 2. Obtaining a comprehensive understanding of the role of field controlling layers in InGaN LEDs. 3. We have undertaken a program of research on GaN based structures in which the electric field which limits the efficiency is reduced. 4. Obtained more detailed understanding of the light generation processes in polar and non polar InGaN quantum wells. |
Exploitation Route | The results of our work are available to the UK manufacturers of LEDS enabling them to be more competitive in this demanding market. |
