Abstract

A method of producing III-V materials by reducing a complex salt in a hydrogen atmosphere is shown. For example, complex salts reduce to InP or GaAs. The salts are conveniently prepared by coprecipitation from a salt solution or by other methods. The stoichiometry can be modified by applying an overpressure of the more volatile element or elements during reduction.
