摘要：
The electronic and transport properties of phosphorene nanoribbons with different edges and widths are studied by using the first-principles calculations together with non-equilibrium Green's function. The band structures of zigzag phosphorene nanoribbons (ZPNRs) show the metallic characteristics when the nanoribbon width is over 6. But for the armchair phosphorene nanoribbons (APNRs), its band gap gradually decrease when the nanoribbon width is over 2. It can be found that both APNRs and ZPNRs appear negative differential resistance (NDR), namely, there is great potential in designing nanoelectronic devices.
