High Performance Long-wave Infrared Focal Plane Arrays based on III-V Antimonide Superlattices

In Phase II, the Attollo team proposes to investigate the growth and fabrication techniques of LWIR SLS and associated variants to meet the target objectives. Our plan is to push the envelope further by increasing the absorption coefficient, improving the material quality and carrier lifetime, and reducing any surface leakage contribution from detector fabrication. At the end of Phase II, we expect to demonstrate a LWIR VGA format FPA with a large well capacity and outstanding pixel response and dark current uniformity.
