Dr. Dongkeun Ki is an Associate Professor of the Department of Physics at the University of Hong Kong (HKU). He received his B.S. and Ph.D. degrees in Physics from POSTECH in 2004 and 2010, respectively, after which he moved to University of Geneva in Switzerland for his postdoctoral research under the supervision of Prof. Alberto Morpurgo. Dr. Ki’s research mainly focuses on discovering and understanding new quantum transport phenomena in low-dimensional systems by engineering their electronic bands using various state-of-the-art nanofabrication techniques. Materials of interest span widely from 1D nanowire to 3D bulk that include 2D materials, topological materials, and artificially designed van der Waals heterostructures. Throughout the investigation, Dr. Ki aims to understand and learn to control the underlying physical processes, expand our view of electronic materials, and contribute to the development of the new device applications.
