Abstract
Abstract 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 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 chalcogenides by employing an N-type rather than an intrinsic substrate.
