Innovative Long Wavelength Infrared Detector Workshop Proceedings
Abstract
The focus of the workshop was on innovative long wavelength infrared (LWIR) detectors with the potential of meeting future NASA and DoD long duration space application needs. Requirements are for focal plane arrays which operate near 65K using active refrigeration with mission lifetimes of five to ten years. The workshop addressed innovative concepts, new material systems, novel device physics, and current progress in relation to benchmark technology. It also provided a forum for discussion of performance characterization, producability, reliability, and fundamental limitations of device physics. It covered the status of the incumbent HgCdTe technology, which shows encouraging progress towards LWIR arrays, and provided a snapshot of research and development in several new contender technologies. These contenders span quantum wells, heterojunctions, and superlattices in columns 2-6, 3-5 and 4 semiconductor materials and promise producible LWIR arrays with the required performance. The workshop also included a session on new innovations for high performance thermal detectors.
