摘要:
We performed a first-principles study on Fe-, Co-, and Ni-terminated zigzag phosphorene nanoribbons (ZPNRs) with different widths. Magnetic edges were observed for Fe-and Co-terminated ZPNRs, whereas Ni-terminated ZPNRs were nonmagnetic. Interestingly, magnetism could be induced in Ni-ZPNRs by external electric fields, and the distribution of the magnetic moments could be tuned by the direction of the electric fields. Furthermore, Fe-ZPNRs and Co-ZPNRs exhibit semi-metallic and metallic characteristics, respectively, whereas Ni-ZPNRs are mainly semiconductors with band gaps generally increasing monotonously with the increase in nanoribbon width. These fascinating properties of iron-group atom terminated ZPNRs indicate their great potential applications in future spintronics, optoelectronics, and information technologies.
