Research Interest:
I am interested in application oriented problems. By training, I am an experimental condensed matter physicist, in particular electronic structure measurement with photoelectron spectroscopy (XPS, UPS, ARPES and IPES). My reserch revolves around increasing efficiencies of photovoltaic and light emitting devices. I am currently exploring noval methods to enhance light extraction in light emitting diode (LED) with finite domain time difference (FDTD) simulation and optical measurements.
