Our research focuses on epitaxial growth and characterization of several II-VI, III-V and IV-IV semiconductors such as CdTe, CdS, ZnTe, BN, and SiC for various solid state devices. Our accomplishments include the first demonstrations of p-type doping of HgCdTe by metal-organic vapor phase epitaxy (MOVPE), p-type doping of ZnSe by MOVPE using phenylhydrazine, several in-situ grown infrared devices in HgCdTe, and development of an epitaxial lateral overgrowth (ELO) process for CdTe on Si. Our current research is focused on developing Si neutron detectors with high efficiency, CdTe solar cells with high Voc, growing silicon carbide epitaxial films for use in high-power, high-temperature, and high-voltage devices, and, depositing highly conformal passivation films for complex IR detector focal plane arrays.
