Abstract: A semiconductor structure for providing an epitaxial zinc oxide layer having p-type conduction for semiconductor device manufacture and methods of depositing the p-type zinc oxide layer. A zinc oxide layer is deposited epitaxially by molecular beam epitaxy on a crystalline zinc oxide substrate. The zinc oxide layer incorporates a p-type dopant, such as nitrogen, in an atomic concentration adequate to provide p-type conduction. The p-type zinc oxide layer may further incorporate an atomic concentration of a compensating species, such as lithium, sufficient to electronically occupy excess donors therein so that the efficiency of the p-type dopant may be increased.
