Description

We perform both theoretical and experimental researches on III-V and II-VI semiconductor-based quantum-well (QW) and superlattice (SL) infrared (IR) detectors, such as HgTe/CdTe, InAs/InGaSb, and GaAs/AlGaAs QWs and SLs. We investigate the band structure, optical absorption, quantum efficiency, dark, and photo-current of these materials and detectors, as well as new designs of surface-plasmon enhanced, frequency tunable and polarization-sensitive IR detectors. We are also interested in silicon visible detector arrays hybridized with CMOS readout circuits. Available laboratory equipment includes Fourier-transform infrared spectroscopy, time-resolved photo-luminescence spectroscopy for carrier lifetime measurement, and all the equipment necessary to fully characterize detector performance from room temperature to cryogenic temperatures. Very recently, we are expanding our research interest to theoretical and experimental studies on proton radiation degradation of electronic and optoelectronic devices.
