Abstract:
A method of fabricating p-type III-V material utilizing HVPE techniques, the method comprising the steps of:locating at least one Group III metal in a source zone of a reaction chamber;locating a substrate within a growth zone of said reaction chamber;locating at least one acceptor impurity metal in said source zone;introducing a halide reaction gas into said source zone to form at least one halide metal compound;transporting said at least one halide metal compound to said growth zone;introducing a reaction gas into said growth zone, said reaction gas containing at least one Group V element;growing a first III-V layer on said substrate, said first III-V layer formed by said reaction gas reacting with said at least one halide metal compound;transporting said at least one acceptor impurity metal to said growth zone; andgrowing a second III-V layer on said first III-V layer, said second III-V layer containing said at least one acceptor impurity metal, wherein said second III-V layer is a p-type III-V layer.
