Abstract:
A method of growing a p-type III-V material utilizing HVPE techniques, the method comprising the steps of:locating at least one Group III metal in a first source zone of a reaction chamber; locating at least one acceptor impurity metal in a second source zone of said reaction chamber; locating a substrate within a growth zone of said reaction chamber; heating said substrate to a first temperature; heating said at least one Group III metal to a second temperature; heating said at least one acceptor impurity metal to a third temperature; introducing a halide reaction gas into said first 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; introducing an inert gas into said second source zone; flowing said inert gas through said second source zone in order to deliver said at least one acceptor impurity metal to said growth zone; and growing said p-type III-V layer through a reaction of said reaction gas and said at least one halide metal compound, wherein said p-type III-V layer contains said at least one acceptor impurity metal.
