摘要:
TO PRODUCE A P-CONDUCTIVITY TYPE WIDE BAND GAP SEMICONDUCTOR MATERIAL, A III-V COMPOUND SEMICONDUCTOR LAYER IS FIRST VACUUM EVAPORATED ONTO AND THEN DIFFUSED INTO A CRYSTALLINE II-VI COMPOUND SEMICONDUCTOR SUBSTRATE, SPECIFICALLY A ZINC CHALCOGENIDE. THE RESULTING HYBRID CRYSTALLINE MATERIAL IS DOPED BY SIMULTANEOUS OR SEQUENTIAL INFUSION OF ZINC ATOMS IN SUBSTITUTION FOR ATOMS OF THE GROUP III ELEMENT. THE PROCESS MAY BE USED FOR THE DIRECT PRODUCTION OF P-N JUNCTIONS IN ZINC CHALOGENIDES BY EMPLOYING AN N-TYPE RATHER THAN AN INTRINSIC SUBSTRATE.
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.
摘要:
A composite of a substrate crystal is disclosed having a compound of the JQ type formulation where J is at least one element of group IIa and Q is at least one element of group VIIa having a film compound formed on the substrate which is of the JQ type formulation where J is at least one element of the group IIb and Q is at least one element of the group VIa. The process for making these composites shows simple and easily controllable steps and provides criteria for obtaining desired film thickness at relatively rapid deposition rates.

摘要:
A PHOTOELECTRIC ELEMENT FOR RECORDING INFORMATION HAVING THREE SOLID LAYERS SUPERIMPOSED IN CONTIGUOUS RELATION INCLUDING AN ELECTRON CONDUCTING LAYER, AN ELECTRON SENSITIVE LAYER AND A PHOTOCONDUCTIVE LAYER. THE PHOTOELECTRIC ELEMENT IS EXPOSED TO RADIATION TO CHANGE THE CONDUCTIVITY OF THE PHOTOCONDUCTIVE LAYER IN ACORDANE TO A DESIRED PATTERN AND IS SUBSEQUENTLY EXPOSED TO AN ELECTRON BEAM TO PRODUCE COLORING IN THE ELECTRON SENSITIVE FILM IN ACCORDANCE WITH THE PATTERN OF RADIATION RECEIVED.
