Current status and technology of the HgCdTe IR detector in Korea

Abstract

The progress and current status of HgCdTe infrared detector in Korea during the last ten years is reviewed and future perspectives of infrared detector research and development are also given The research and development of HgCdTe infrared detector was started in 1987. In the first five years, we had focused on the material growth, especially liquid phase epitaxy (LPE) by slider method and single element MWIR photovoltaic detector with large active area was realized with this LPE material. After that, the development of the linear array infrared detectors including photoconductive and photovoltaic devices was initiated and will be finished very soon. During this period we developed the travelling heater method (THM) for the use of the linear arrays. On the other hand MBE growth of HgCdTe was started for a specific applications and MOVPE process was employed for the two-color infrared development Focal plane army program will be initiated very soon.
