Introduction

Shu-Wei Wang (王書瑋) is an assistant professor at the Department of Electrical Engineering, National Cheng Kung University, Taiwan. He received Ph.D. in Physics from the University of Cambridge after he obtained his M.S. degree from National Taiwan University and B.S. degree from National Cheng Kung University. He specializes in experimental condensed matter physics, including the study of 2D materials, topological materials, and III-V semiconductors. He is an experienced experimentalist in nanodevice fabrication, low-noise transport measurement, and scanning probe microscopy, from room temperature to cryogenic environment. 
His research experience and interests include:
- Investigating the magnetic and electrical properties of topological insulators and magnetically-doped topological insulators (e.g. vanadium- and chromium-doped bismuth antimony telluride) using transport measurements and various scanning probe microscopy techniques, e.g. AFM, EFM, MFM, KPM, SHPM, and SGM.
- Studying the carrier transport behavior in monolayer and bilayer graphene using transport measurements and scanning probe microscopy.
- Studying the exchange coupling at the interface between magnetic materials and topological insulators, aiming for realizing all-electric low-power spintronic devices
using magnetic switching driven by spin-orbit torque.
- Studying the carrier transport behaviour in van der Waals materials, especially the transition metal dichalcogenide thin-film field-effect transistors. 
- Building an Akiyama probe-based scanning probe microscope system that can be operated between 1.5 K and room temperature.

Our research interest lies in the electrical and magnetic properties of semiconductors and nanomaterials, including topological insulators, III-V compounds, and 2D materials. We are particularly interested in the transport behavior of charge carriers and topological properties of matter in low-dimensional systems. By combining high magnetic field and low-temperature measurement techniques, we study the exotic electronic states and topological phases in quantum matter and nanomaterials.
