The growth of mercury cadmium telluride (Hg(1-x)Cdx Te) alloys is carried out by the pyrolytic decomposition of a mixture of Cd and Te alkyls in an atmosphere of Hg vapor; the ternary alloy is deposited as an epitaxial film on a CdTe single crystal substrate. The substrate is carried on a heated sus...
