Chao-Hui was born and raised in Taiwan. He was granted the PhD degree in electrical engineering by National Tsing Hua University (NTHU), Taiwan in 2014 for his work on high-speed graphene electronics and ferromagnetic oxide materials. Subsequently, he worked as a postdoctoral researcher in the same research group at NTHU for exploiting novel two-dimensional (2D) materials and their applications in future electronics. In January 2019, he joined the NRL to work with Prof. Banerjee. His primary research expertise lies in developing and using various growth techniques including CVD and MOCVD to synthesize van der Waals 2D crystals and thin films, including 2D semiconductors, 2D semimetals/metals, 2D insulators, as well as complex 2D heterostructures. He is also skilled in fundamental device physics and characterization of 2D material systems.
