My research focuses on studying low dimensional materials using scanning probe microscopy and magneto transport techniques.
My lab is devoted to the study of electronic properties of new materials. The main experimental techniques we use are low temperature high field transport and scanning probe microscopy (SPM). The former provides information of the electron movement at a mesoscopic (or macroscopic) level while the later at a microscopic level.
Currently we are studying 2 dimensional (2D) materials. Using nanofabrication, we make nanoelectronic devices with these 2D materials, which can be studied by either transport or the SPM.
