Research abstract

We propose to design and demonstrate a unique photodetector structure for the mid-infrared 2-5 um spectrum. The innovation consists of combining an optical resonant cavity heterojunction phototransistor and negative differential switch into a single device using multi-quantum-well epitaxial layers. In Phase I, we will investigate the growth of GaInAsSb and AlGaAsSb alloys via metal organic molecular beam epitaxy ( "MO-MBE" ), and characterize thin quantum well layers for crystal defects and band discontinuities. In Phase II, we will construct and optimize working devices and utilize these devices in gas sensing instruments. Prof. Jian Zhao (Rutgers University) and Dr. Glen Cullen (SRI David Sarnoff Research Center) will consult on this project.
