Abstract: We recently reported mid-wavelength infrared (MWIR) InAs/InAsSb type II strained-layer superlattice (T2SLS) unipolar barrier detectors and focal-plane arrays with significantly higher operating temperature than InSb. Herein, we document the development leading to the MWIR InAs/InAsSb T2SLS… read more here.

Abstract: We show that Sb substitution for As in a MBE grown InAs/InAsSb strained layer superlattice (SLS) is accompanied by significant strain fluctuations. The SLS was observed using scanning transmission electron microscopy along the [100] zone… read more here.
