Abstract:
1. A solid state device comprising a p-n junction containing a p-type group II-VI semiconductor material and an n-type semiconductor material, wherein the p-type group II-VI semiconductor comprises a single crystal 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 selected from nitrogen, phosphorus, arsenic, antimony, bismuth, copper, and chalcogenides of the foregoing, and mixtures thereof, wherein the p-type dopant concentration in the group II-VI semiconductor is greater than about 10 16 atoms·cm −3 , wherein semiconductor resistivity is less than about 0.5 ohm·cm, and wherein the carrier mobility is greater than about 0.1 cm 2 /V·s, and wherein the p-type group II-VI semiconductor material has a luminescent peak at 3.357 eV.
