Abstract: We investigated the structure and electronic properties of β12borene nanoribbons (BNRs) by using first principles calculations. The results show that the bare BNRs with different width and cutting direction has metallicity, and the stability of the BNRs increases with the increase of width. The hydrogen atom is used to passivate the B atom at the boundary vertex of BNRs, most BNRs is metallic and a few BNRs is semiconductor.

Key words: first principle, borene nanoribbon, energy band structure
