Type II strained layer superlattice: A potential future IR solution

Type II strained layer superlattice (SLS) has been making tremendous progress in the past few years funded by the Missile Defense Agency Advanced Technology Directorate (MDA/DV) under the Passive EO/IR Program. SLS has shown great potential as a future solution for infrared military systems. In this presentation, the most recent progress in SLS development will be presented. The presentation will also discuss the comparison of SLS with mercury–cadmium–telluride (HgCdTe) using Rule 07, SLS minority carrier lifetime issues, and future directions.
