A half-metal is any substance that acts as a conductor to electrons of one spin orientation, but as an insulator or semiconductor to those of the opposite orientation. Although all half-metals are ferromagnetic (or ferrimagnetic), most ferromagnets are not half-metals. Many of the known examples of half-metals are oxides, sulfides, or Heusler alloys. WebApr 13, 2024 · 邀请直播讲解. At B3LYP level of theory, we predict that the half-metallicity in zigzag edge graphene nanoribbon (ZGNR) can be realized when an external electric field is applied across the ribbon. The critical electric field to induce the half-metallicity decreases with the increase of the ribbon width. Both the spin polarization and half ...

WebMar 15, 2024 · Half-Metallic Gap (E HM) is an essential striking feature of the half-metallic ferromagnets and useful for studying the half-metallicity. It can be determined by finding the minimum value either of E F -E v top or E c bot -E F , where, E v top and E c bot represent the energy equivalent to maxima of valence band (VB) and minima of … WebApr 13, 2024 · 邀请直播讲解.
