Structure dependent electronic and magnetic properties of graphitic GaN–ZnO nanoribbons

Abstract

We investigate the electronic and magnetic properties of GaN–ZnO nanoribbons with density functional theory methods. The obtained large binding energies suggest that these graphitic nanostructures are stable and can hence be effectively synthesized. Their calculated properties strongly depend on the edge atomic configuration: armchair nanoribbons are non-magnetic semiconductors and zigzag ones are half-metals with net magnetism depending on the ribbon width.
