摘要:
A composite comprises a substrate of monocrystalline structure which is either a hexagonal, cubic, rhombohedral or orthorhombic, and a monocrystalline layer on the substrate of a JQ compound formulation wherein J is at least one element selected from the group consisting of cadmium, zinc and mercury, and wherein Q is at least one element selected from the group consisting of sulfur, tellurium, selenium and/or oxygen. An alkyl or hydride type dopant may be used to provide a homogeneously doped layer. Processes for making the layer composition and for making the composite are described.

[Also in Division C1 ] In a process of epitaxial deposition of a semiconductor on a single crystal substrate, a densely nucleated first semi-conductor layer, formed by thermal decomposition of a hydride, is applied initially, before the main part of the semi-conductor film is added by thermal decomposition of a halide. Both the hydride and the halide may be carried in a hydrogen stream. The substrate may be sapphire, Be oxide, Mg oxide, Si, Ge, B, chrysoberyl, Ca fluoride, a group III-V compound or a group II-VI compound. Ge may be deposited from germane or other Ge hydrides, followed by trichlorogermane or Ge tetrahalides. Si and B may also be deposited. Semi-conductor devices may be fabricated in the films so formed.
