Research Experience
Strong Interface-Induced Spin–Orbit Interaction in Graphene on BiSe2O5, XJTU
Role: Individual Project, Supervised by Professor Zhe Wang, Collaborated with Haibo Xie
The project aims to stack graphene on BiSe2O5 to induce spin-orbit coupling, inspired by Professor Zhe Wang's work on WS2 and WSe2. It involves weak anti-localization effect measurements, analysis of Shubnikov-de Haas oscillations, and ab initio calculations of interface-induced SOI.
- Independently responsible for device fabrication, theoretical calculations, experimental design, and data processing.
- Collaborated with graduate student Haibo Xie for etching and data measurement.
- Currently analyzing data to draw conclusions from ongoing experiments.
