Nitride semiconductors are in the process of revolutionising the efficiency of lighting, significantly reducing energy consumption and the consequent impact on the environment. Currently, InGaN/GaN quantum well structures are typically grown on the c-plane of the wurtzite crystal phase and then used to fabricate highly efficient LEDs emitting in the blue that are combined with a yellow phosphor to make the ‘white’ light suitable for illuminating homes and offices. A more efficient and controllable approach would be to generate white light by mixing the output of multiple LEDs emitting different colours. However, the efficiency of the current generation of nitride LEDs drops significantly as the emission wavelength increases. This reduction may be associated with the strong polarisation field across the quantum well that forms as a consequence of the wurtzite crystal phase and growth direction used.
This post is funded by a Platform Grant from the Engineering and Physical Research Science Council to study recombination in nitride quantum structures produced by alternatives to c-plane wurtzite growth.
The successful candidate will join a team of physicists who will work together to understand the optoelectronic properties of this novel material in order to exploit its potential as the basis for efficient LEDs emitting in the green and amber part of the spectrum. The project is in collaboration with the Department of Materials and Metallurgy at the University of Cambridge, who will grow and structurally characterise the samples.
The successful candidate will be responsible for the optical characterisation of GaN films and InGaN/GaN quantum well structures grown by and structurally characterised by our collaborators. In particular, low temperature steady-state and transient photoluminescence experiments will enable the recombination process and its dependence on defect density, microstructure and carrier localisation to be understood.
