Abstract:
1. A persistent p-type group II-VI semiconductor material comprising a thin film of a single crystal group II-VI semiconductor comprising atoms of group II elements and atoms of group VI elements, wherein the group II-VI semiconductor is doped with a p-type dopant to form one or more ternary compounds:, and wherein the single crystal group II-VI semiconductor has a crystal lattice comprising vacancies of atoms of the group II elements, wherein the p-type dopant replaces atoms of the group VI elements in the semiconductor material under conditions which inhibit formation of chemical bonds between atoms of group VI elements and the p-type dopant and inhibit the formation of volatile reaction products of the group VI elements and the p-type dopant, wherein the group II-VI semiconductor is doped with a p-type dopant at a temperature below about 450° C.
