Abstract
Detailed theoretical calculations of Auger and radiative recombination rates for an optimized InAs/InxGa1-xSb superlattice (SL) and bulk Hgx Cd1-xTe (MCT) show that 300 K background limited operation for a 60-de grees field of view can be theoretically achieved up to 130 K for the 11 mum SL and up to 185 K for 5 mum MCT. The SL structure is theoretic ally superior to MCT for 11 mum operation. The converse is true at 5 m um.
