Abstract
Type II strained-layer superlattices promise superior performance as detectors in the LWIR and VLWIR wave-length regimes due to their potential for suppressing Auger recombination (and thus dark currents). These predictors for lower Auger rates have been verified experimentally, however the Shockley-Read-Hall recombination times remain shorter than for competing materials. Recent advances in understanding the interaction of defect/donor states with interfaces in strained materials indicates that in these short-period superlattices the behavior of defects and donors can be very different from in the bulk. The current understanding of these issues will be reviewed.
