Major Research Areas:

InGaN quantum well and quantum dot LEDs, high power nitride based HEMTs, and Ferroelectronics

III-V wide bandgap semiconductor devices: We are focusing on device modeling of Al/GaN HFETs, which are applied in high power and high frequency area.

II-VI and III-V wide bandgap optoelectronic devices: Device modeling of quantum well/dot light emitting diodes, Analysis of carrier transport, emission and absorption properties.

Smart sensor FETs: We are interested in studying the junction properties of ferroelectric/semiconductor devices, which can be applied in memory, optical modular, waveguide, and sensor areas.
