Design and Fabrication of High-Performance LWIR Photodetectors Based on Type-II Superlattices

Abstract

Antimonide-based Type-II superlattices represent the most promising material system capable of delivering more producible, large-format, reduced pixel pitch, long-wavelength infrared (LWIR) focal plane arrays (FPAs) for persistent surveillance applications. Improvement in material quality and processing technique, as well as evolutionary modifications in device architecture have demonstrated the advantages of the material system over alternatives, and proven it as a viable candidate for the next generation infrared imaging.
