    摘要: Metal-insulator-semiconductor devices are formed on III-V semiconductors utilizing a pnictide rich insulating layer. The layer may be applied by vacuum evaporation, sputtering, chemical vapor deposition, and from a liquid melt. Gallium arsenide, indium phosphide, and gallium phosphide substrates are insulated with an alkali metal high pnictide polypnictide, preferably a polyphosphide, having the formula MP.sub.x where x is equal to or greater than 15, including new forms of phosphorus grown in the presence of an alkali metal where x is much greater than 15. A KP.sub.15 layer is preferred. They may also be insulated with a layer of a solid elemental pnictide, namely phosphorus, arsenic, antimony or bismuth applied by one of the above named processes. An elemental phosphorus layer is preferred. A silicon nitride, Si.sub.3 N.sub.4, layer may be added on top of the pnictide layer to increase the breakdown voltage of the insulating layer.

    摘要: A method and apparatus are provided for producing fine quality pnictide films by vacuum evaporation and molecular beam deposition. A pnictide source, preferably phosphorous, is heated to produce a continuous supply of vapor species, preferably P.sub.4. The vapor species is cracked by a heated tungsten wire positioned adjacent the pnictide source to produce P.sub.2 molecules. A second tungsten wire cracker is located adjacent a substrate to prevent the recombination of P.sub.2 molecules into P.sub.4 molecules. The P.sub.2 molecules are deposited on the substrate and condense into amorphous pure phosphorous shiny red films. A separate source of alkali metal intercalate, preferably KC.sub.8, may also be heated to provide an alkali metal vapor for producing films of alkali metal polypnictide films, preferably KP.sub.x where x is equal to or greater than 15, to be deposited on the substrate. Fine quality films may also be deposited on a substrate by a molecular beam apparatus providing a continuous source of pnictide vapor species and a cracker disposed between the exit of a pnictide collimator and the substrate.
