Reaserch Interest

We focus on the transport studies of low-dimensional quantum materials under extremely low temperatures and strong magnetic fields. The experimental methods are mainly on fabricating functional devices by using the nano-patterning technique and in-situ tuning the transport properties through dielectric gating and electrochemical intercalation. The interested fields are two-dimensional layered superconductor materials, interfacial superconductivity, quantum anomalous Hall effect, Majorana fermions, etc.

Graduate students interested in these fields are very welcome to join us! Meanwhile, the research assistant and postdoc positions are opening now!
