Chengjie Zhou is currently a PhD student in the Physics Department at HKUST and will graduate this summer. He received his bachelor's degree in physics from the Southern University of Science and Technology. his current research focuses on using van der Waals material-based, gate-tunable resonant tunnelling diodes to probe the electronic properties of small- and large-angle twisted homo-bilayer transition metal dichalcogenides, magic-angle twisted bilayer graphene, and related systems. He is broadly interested in moiré-related physics, particularly in exploring new candidates for the integer and fractional quantum anomalous Hall effect, the quantum spin Hall effect, and in the search for non-Abelian states in these moiré systems.
