Patent ID: 7141489

Claim:
A method of preparing p-type group II–VI semiconductor material comprising: obtaining a self supporting substrate surface; and depositing a thin film of a 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 one or more p-type dopants on the substrate surface under deposition conditions in which the group II atoms, group VI atoms, and p-type dopant atoms are combined as the thin film of group II–VI semiconductor, wherein the p-type dopant is selected from nitrogen, phosphorus, arsenic, antimony, bismuth, copper, and chalcogenides of the foregoing, and mixtures thereof, wherein the resulting thin film of group II–VI semiconductor is a persistent p-type semiconductor and the p-type dopant concentration in the group II–VI semiconductor is greater than about 10 16 atoms·cm −3 and wherein the semiconductor resistivity is less than about 0.5 ohm·cm.
