Xuejun Xie received his Bachelor of Science degree in Applied Physics from Beijing Institute of Technology. During his undergraduate years, he was the recipient of National Students Innovation Project Funding on "Carbon based graphene capacitor", the Beijing Students Innovation Project Funding on "3D PCB Printer", as well as the “T-more” scholarship for his outstanding academic potential. During his undergraduate years, he was associated with the Key Laboratory of Cluster Science in Beijing Institute of Technology for two years as one of the founding members in Prof. Liangti Qu’s group, which emphasized on dynamic micrometer measurements and CVD graphene fabrication. In Fall 2011, he joined the Nanoelectronics Research Lab (NRL), at the University of California, Santa Barbara, as a PhD student in the Electrical and Computer Engineering Department, under the supervision of Prof. Kaustav Banerjee. His doctoral research was focused on exploring the potential of 2D materials for creating quantum dot arrays needed for quantum computing, neuromorphic transistors for artificial intelligence, and light emitting material for augmented reality targeted future displays. He was also a key contributor to the demonstration of several breakthrough device innovations from the NRL, including the first 2D-channel tunnel-FET and the first MoS2-FET biosensor. Xuejun received his Ph.D. degree from the Department of Electrical and Computer Engineering in Fall 2019.
