Personal profile
Overview
I graduated with an MPhys in Physics from the University of Liverpool in 2022, specialising in defect analysis of thin film CdTe solar cells. My interest in semiconductor devices led me to join the CDT in Compound Semiconductor Manufacturing, through which I gained an MSc in Compound Semiconductor Physics from Cardiff University in 2023. During my time in Cardiff, my research focus continued to look into defects in compound semiconductors through electrical and optical characterisation techniques, as I analysed GaN-based materials. My current PhD project looks to study point defects in wide bandgap semiconductors and assess the impact they have on device performance, through the application of Laplace (high resolution) Deep Level Transient Spectroscopy.
My supervisor is Prof Matthew Halsall and I work with specialists in this topic area including Prof Anthony Peaker, Dr Vladimir Markevich and Dr Ian Hawkins.
