InAs/GaSb type II super-lattice is a novel infrared material with the theoretical promise of better performance than MCT and InSb. In view of the maturity of III-V compound materials growth and device technology,it is easy to obtain InAs/GaSb type II super-lattice material for uniform large formats and dual/multiple color infrared detectors. At present,InAs/GaSb type II super-lattice material is regarded as a primary material for the third generation infrared detectors,which may gradually replace MCT and InSb. The basic theory,the research on materials growth and device structure of InAs/GaSb type II super-lattice infrared detector are presented. Research progress of InAs/GaSb type II super-lattice infrared detector is summarized.
