Abstract
We present firstprinciples calculations to study the heterojunction between a wurtzite GaN0001 film and a hexagonal hbox Gd 2hbox O 30001 substrate We report that the most favorable hbox Gd 2hbox O 30001 surface is O terminated Using the work of adhesion of isolated GaN and hbox Gd 2hbox O 3 slabs our calculated interface energies suggest that the graphiticlike GaN films are fully relaxed at hbox Gd 2hbox O 30001 platforms thereby leading to Gapolarity in the GaN0001 epitaxial film Our findings agree with previously reported results
