    Abstract : Type-II Superlattice (T2SL) detectors have revolutionized the field of infraredimaging, establishing themselves as the forefront technology in defense, space,and industrial applications. These detectors enable larger formats and higheroperating temperatures (HOT) that minimize the need for bulky and energyconsumingcryogenic cooling, paving the way for imaging systems with reducedSize, Weight, and Power (SWaP).
