Abstract

The technology of producing HgCdTe materials, detectors, and arrays is rapidly maturing. In this paper, the performance and producibility of 2.5 - 14 micrometers LPE HgCdTe epilayers, as well as PC and PV detectors, are presented. The diodes show no degradation after a 95 degree(s)C baking for a period of two weeks. Fully operational linear arrays are produced at Fermionics Corporation. Most of the arrays show excellent uniformity. From the cost and quality point of view, these products are currently very competitive. These results demonstrate the producibility of HgCdTe materials, detectors, and arrays.
