Abstract : The purpose of this work was to (1) further develop a technique for reproducibly growing a homogeneous, predetermined composition of mercury-cadmium-telluride in single-crystal form by epitaxy, (2) to test this material for significant characteristics, and (3) to fabricate and evaluate infrared radiation detectors from the grown material. Work was initiated under this program to exercise quantitative control over the growth processes, and a special apparatus was built and tested toward this end. Analytical data were obtained to relate semiconducting properties of deposited material with crystal growth parameters. Infrared detectors were fabricated from epitaxial material, and their properties were measured to gain further understanding of the exact mechanism of the growth of Hg(x)Cd(1-x)Te in an open-tube epitaxial system.
