Computational Investigation on Structural and Physical Properties of AlN Nanosheets and Nanoribbons
Abstract:Through first-principles computations, we investigated the structural, electronic and magnetic properties of two-dimensional AlN single layer and one-dimensional AlN nanoribbons. AlN single layer and nanoribbons quit the Wurtzite configuration and adopt a graphitic-like structure after geometry optimization. Both hydrogen-terminated zigzag and armchair AlN nanoribbons have a direct band gap, which increases monotonically with increasing ribbon width. Bare zigzag AlN nanoribbons have a spin-polarized ground state and are magnetic semiconductors. The results may promote the experimental preparation of AlN nanosheets and nanoribbons and their applications to nanotechnology.
