Research Areas

1. Experimental methods to reveal the spatially resolved electronic properties in functional materials
     Mainly based on the scanning probe microscopy (SPM), to utilize the relevant  modes and improve their capabilities in dissecting the distributional characters that closely related with the performance of photoelectric materials and device structures.
2. Micro-scale physics of optoelectronics in quantized system 
    By probing the electrons (holes) in individual confined structures, to study the quantized states they populate and the photon-electron interaction in low-dimensional systems.
