State of the art Type II antimonide based superlattice photodiodes for infrared detection and imaging
Type II InAs/GaSb Superlattice (SL) a system of multi interacting quantum wells was first introduced by Nobel Laureate L. Esaki in the 1970s. Since then, this low dimensional system has drawn a lot of attention for its attractive quantum mechanics properties and its grand potential for the emergence into the application world, especially in infrared detection. In recent years, Type II InAs/GaSb superlattice photo detectors have experienced significant improvements in material quality, structural designs and imaging applications which elevated the performances of Type II InAs/GaSb superlattice photodetectors to a comparable level to the state of the art Mercury Cadmium Telluride. We will present in this talk the current status of the state of the art Type II superlattice photodetectors and focal plane arrays, and the future outlook for this material system.
