Abstract

The electronic and structural properties of BN nanowires are studied by using first principles calculations based on density functional theory. In order to understand dependence of the electronic band structures and density of states on nanowire diameters and shapes, we consider BN nanowires with various diameters in the [001] growth direction. Our results reveal that the effect of changing diameter on electronic properties plays an important role and the band gap can be tuned by changing the wire diameter.
