Professional Experience and Skills
During my Ph.D. (supervised by Prof. Hong-Jun Gao), I collaborated with a Createc engineer to set up a scanning tunneling microscopy (STM) system (working temperature: 4.8 K), and was responsible for the system's operation and maintenance, ensuring its stability and high performance. My research focused on the fabrication of van der Waals heterostructures using two-dimensional materials such as graphene and boron nitride through micro- and nanofabrication techniques, and the investigation of novel correlated and topological states in moiré heterostructures.
As a postdoctoral researcher (supervised by Prof. Hong-Jun Gao), I participated in building a Unisoku 1600 STM system (working temperature: 30 mK; magnetic field: 9-2-2 T) and was responsible for the system's operation and maintenance. My research focused on bulk quantum materials and exotic quantum phases such as charge density wave and superconductivity.
