表面锌键的部分表面钝化是传统体积掺杂的替代方法，可在 ZnO 纳米线中诱导铁磁性。部分 F 钝化的纳米线表现出半金属基态特性。当 ZnO 的维数从 2 维（表面）减少到 1 维（纳米线）时，铁磁稳定性得到改善。表面钝化方法可适用于调节一般纳米材料的磁性。© 2010 WILEY-VCH Verlag GmbH & Co. KGaA，Weinheim。
Partial surface passivation of surface zinc bonds is an alternative approach to conventional volume doping to induce ferromagnetism in ZnO nanowires. Nanowires with partial F passivation exhibit half-metallic ground-state properties. The ferromagnetic stability is improved when the dimensionality of ZnO decreases from two (surfaces) to one (nanowires). The surface passivation approach may be applicable to modulating the magnetic properties of general nanomaterials.© 2010 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
