A persistent p-type group II-VI semiconductor material is disclosed. The
group II-VI semiconductor includes atoms of group II elements, atoms of
group VI elements, and one or more p-type dopants. The p-type dopant
concentration is sufficient to render the group II-VI semiconductor
material in a single crystal form. The semiconductor resistivity is less
than about 0.5 ohmcm, and the carrier mobility is greater than about 0.1
cm.sup.2/Vs. Group II elements include zinc, cadmium, the alkaline earth
metals such as beryllium, magnesium calcium, strontium, and barium, and
mixtures thereof. Group VI elements include oxygen, sulfur, selenium,
tellurium, and mixtures thereof. P-type dopants include, but are not
limited to, nitrogen, phosphorus, arsenic, antimony, chalcogenides of the
foregoing, and mixtures thereof.
