Overview
I am a physics PhD student with a background in silicon semiconductors, apart of the compound semiconductor CDT. At Cardiff University I am currently researching quantum dot lasers with the aim to improve performance, and achieve higher quality yields of devices.

Biography
I started my journey at the university of Salford, where I was introduced to semiconductors through studying Erbium implanted Silicon (EIS) semiconductors, measuring properties such as resistivity, Seebeck effect, Raman scattering, and electron paramagnetic resonance spectroscopy, modelling the spectra. Then I joined the compound semiconductor CDT, where as part of my PhD project I am investigating the variation of quantum dot laser characteristics across 150 mm wafers and developing on wafer characterisation. To enable identification of areas on the wafer that meet specific device specification prior to full fabrication and understand the origin of the variability.
Honours and awards
