Recent advances in IR imaging focal plane arrays technology at UWA

Research and development of semiconducting HgCdTe material and devices commenced in 1959 [1]. Due to its outstanding natural properties, such as tuneable band gap and high quantum efficiency, HgCdTe has dominated the high performance end of the infrared detector market for decades. In this paper, we present recent advances in the material growth and device fabrication of HgCdTe infrared imaging focal plane arrays (IRFPAs) at The University of Western Australia (UWA). Also presented are some of the major achievements and future outlook.
