Abstract

First-principles calculations reported here illuminate the effects of the interface properties of Al2O3 and graphene, with emphasis on the structural and electrical properties. Various contact interfaces and with different alpha-Al 2O3 surface terminations are considered with on and slightly-off stoichiometric aluminum oxide. We show that depending on whether aluminum or oxygen is...
