Abstract

The BN zigzag nanoribbons (BNZNRs) were examined by first-principles density functional calculations, including structural relaxation. The quantum confinement and edge effects of the BNZNRs produce a magnetic ground state. When the B-edge is hydrogenated, the BNZNRs possess a new state with a spin-resloved Dirac point Fermi surface, which paves a way to realizing spin-polarized massless carriers.
