2 RESEARCH EXPERIENCE Apr Present Postdoctoral Research Associate Center for Low Energy Systems Technology (LEAST) Department of Electrical Engineering, University of Notre Dame, USA o Developed low-voltage and steep subthreshold swing (SS) components for beyond-cmos electronic systems using low-dimensional materials, and explored new concepts for energy-efficient devices to reduce power in electronic systems. o Demonstrated the world s thinnest (3 nm) MoS2 p-n homojunction, and investigated its carrier transport and photoresponse. Mar Apr Postdoctoral Researcher o Proposed a gate-controlled Schottky barrier modulation for superior photoresponse of TMD FETs composed of MoS2 and WSe2. o Proposed a trap-assisted technique for high photocurrent and quantum efficiency in single-layer graphene FET photodetector. Mar Mar Major Research towards Ph.D. o Proposed an application of high-k materials, e.g., Si3N4, ZrO2, and HfO2 to the LSPR excited by Au nanoparticle structure for silicon-based thin film solar cells. Analyzed the enhanced light absorption using Mie theory and FDTD simulation. o Investigated the radial-junction Si nanohole (SiNH) and Si nanowire (SiNW) surface texture for solar cells.
