Novel 3D metallic boron nitride containing only sp 2

As the closest isoelectronic analogue of carbon, boron nitride (BN) shares a similar structure with carbon from 1D nanotubes, 2D nanosheets, and 3D diamond structures. However, most BN structures are insulators, which limits their application. In this work, under the inspiration of the sp 2 hybridized carbon honeycomb, we propose a hexagonal phase of BN consisting of only sp2 bonds ...
