In recent years, Type II InAs/GaSb superlattices grown on GaSb substrate have achieved significant advances in both structural design and material growth, making Type II superlattice infrared detector a rival competitor to the state-of-the-art MCT technology. However, the limited size and strong infrared absorption of GaSb substrates prevent large format type-II superlattice infrared imagers from being realized. In this work, we demonstrate type-II superlattices grown on GaAs substrates, which is a significant step toward third generation infrared imaging at low cost. The device performances of Type II superalttice photodetectors grown on these two substrates are compared.
