Abstract
The theoretical performance of medium wavelength infrared (MWIR) InAsSb-based ternary alloy photodiodes is examined theoretically taking into account thermal generation governed by the Auger and radiative mechanisms. The contribution of spin-off band on carrier lifetime in p-type InAsSb ternary is re-examined due to new insight into composition dependence of spin-orbit-splitting band gap energy. The investigations are carried out for photodiodes operated at room temperature. The effects of doping profiles on the photodiode parameters (R0A product and detectivity) are considered. The theoretical predictions of photodiode parameters are compared with experimental data published in the literature.
