Method for growth of in situ p-type semiconductor films using a group V flux

摘要

A method of growing a p-type doped Group II-VI semiconductor film includes the steps of forming a lattice comprising a Group II material and a Group VI material and generating a first Group V flux by evaporating a solid Group V source material. The first Group V flux is then decomposed to generate a second Group V flux, which is, in turn, provided to the lattice to p-type dope the growing film. The Group V source material may by arsenic such that the second Group V flux may predominantly include dimeric arsenic decomposed from tetrameric arsenic to improve the incorporation of arsenic into the Group VI sublattice of the lattice.
