TuE3.2 - MBE GROWTH AND CHARACTERIZATION OF SB-BASED METAMORPHIC IR PHOTODETECTOR STRUCTURES GROWN ON LARGE MISMATCH SUBSTRATES

Abstract

Abstract

GaSb-based nBn IR photodetectors were grown by MBE using a metamorphic buffer process on 6-inch diameter GaAs and Si substrates. M-nBn epiwafer characteristics and diode performance, including high quality full FPA imagery, will be presented and compared to the same nBn grown on native GaSb.

TuE4.5 - PHOTODETECTOR ARCHITECTURE FOR OPEN CIRCUIT VOLTAGE OPERATION OF MWIR INASSB DETECTORS

Abstract

Abstract

Unlike conventional detectors that rely on photocurrent, the open circuit voltage photodetector architecture relies on a detector operating in zero bias. The output from the detector is coupled to the gate of a FET in sub-threshold region. Radiometric characterization of this detector will be discussed.
