Personal profile

Biography

Dr. Wen Lei is a Professor and an ARC Future Fellow at University of Western Australia and leads the Electronic Materials and Devices Research Lab (EMDRL) at School of Electrical, Electronic and Computer Engineering, University of Western Australia. Since his PhD study (2003), he has been working on the epitaxial growth (MBE, MOCVD and CVD) and characterization of semiconductor thin film materials, and their applications in devices such as detectors, lasers, and solar cells. In the last several years, He holds 2 patents and has published over 70 high profile papers in top journals like Applied Physics Reviews, Physical Review Letters, Small, Analytical Chemistry, Nanoscale, Applied Physics Letters, etc. He was awarded his prestigious ARC Future Fellowship in 2013 and ARC Australian Postdoctoral Fellowship in 2006. He is also a lead guest editor/editorial board member of five international journals and a regular reviewer for various international prestigious journals and funding agencies.
