My Master’s research, conducted from 2017 to 2020 at Sun Yat-sen University, concentrated on the simulation and experimental study of GaN/AlGaN-based heterojunction photodetector/phototransistor. Using the Silvaco TCAD platform, I modeled GaN device structures and characteristics to complement experimental research. I also gained hands-on experience in microfabrication processes in a cleanroom, performing tasks such as photolithography, ICP dry etching, wet etching, electron beam evaporation, magnetron sputtering, and rapid thermal annealing (RTA). Furthermore, I utilized a variety of characterization techniques to study GaN photodetector properties, including I-V and C-V measurements, photoresponse, weak light response, response speed, PL, SEM, and SIMS analyses.
During my PhD research at the Department of Electrical and Electronic Engineering (EEE), University of Manchester (UoM), from April 2022 to the present. My work has focused on the characterization of deep-level defects in GaN/AlGaN-based LEDs materials. This involves the use of Deep Level Transient Spectroscopy (DLTS) and Photoluminescence Spectroscopy (PL) to identify critical defect properties. Additionally, I have employed high-resolution Laplace DLTS (L-DLTS) to resolve closely spaced defect energy levels, providing deeper insights into the electronic properties and behavior of GaN-based materials.
My supervisors are Prof Matthew Halsall and Prof David Binks, and I work with experts specializing in this research area including Prof Anthony Peaker, Dr Vladimir Markevich, and Dr Ian Hawkins.
