Introduction

Hongliang Chang joined the Photonics laboratory of King Abdullah University of Science and Technology (KAUST) in September 2022. He obtained Ph. D. of Engineering in the Institute of Semiconductor, Chinese Academy of Sciences, China in 2021. During his Ph. D., he realized the high-quality epitaxial of the large-match semiconductor system based on 2D materials, and fabricated high-performance DUV optoelectronic devices. His current research focus on the development of wide-band semiconductor film based optoelectronic devices and system for its applications in optical-based wireless communication. He also served as the youth reviewer for Chinese Journal of Luminescence.
