  • Abstract
    Our research goal is to develop InP-based devices as an alternative to QWIPs and HgCdTe for MIR detection. The approach we have pursued for longer wavelength detection on InP is a type-II superlattice consisting of GaxIn1-xAs and GaAsySb 1-y alloys. These structures provide two advantages for MIR detection: large (greater than 700 meV) direct band-gaps, which should lead to a lower thermal carrier generation rate and the ability to adjust the detection wavelength by changing the compositions of GaInAs and GaAsSb and their thickness in the superlattice
