Title: Synthesis and surface engineering of low-dimensional semiconductors for electronics and energy applications

Abstract

Low-dimensional semiconductors, especially two-dimensional (2D) semiconductors, are considered one of the most promising candidates in the field of microelectronics, optoelectronics, and energy, owing to their atomically thin structure that can mitigate short-channel effects, controllable band gaps, and quantum confinement effect. The synthesis of low-dimensional semiconductors, as well as the use of surface and interface engineering for tailoring the electronic properties are essential to broaden their applications. This report summarizes our research on the synthesis and surface/interface engineering of low-dimensional semiconductors, especially two-dimensional transition metal dihalides (TMDC). Element doping and heterogeneous interface engineering are utilized to adjust their physical and chemical properties in order to realize high-performance electronic devices and new energy devices.
