Proton Irradiation Effects on Mid-Wave Infrared InGaAs/InAsSb Superlattice nBn Photodetectors

Type-II superlattice nBn photodetectors based on mid-wave infrared III-V materials have progressed considerably in terms of noise and quantum efficiency. While these traits lend feasibility towards space-based applications, it is necessary to examine the consequences of proton irradiation and investigate strategies for mitigating performance degradation.
