摘要

Two types of self-assembled Fe nanowires (NWs) were grown by molecular beam epitaxy on ZnS(100) surface under high growth/annealing temperature. The type-A Fe NWs orient along the ZnS [110] direction with irregular shape, while the type-B Fe NWs orient along either the ZnS [18 0] or the [810] direction with seemingly straight shape. Detailed high-resolution transmission electron microscopy and selected area electron diffraction studies reveal that both types were single-crystalline with their elongated axis along the < 10 0 > direction family possibly due to the fact that the easy axis of Fe is along this direction. We have proposed a mean-field model to explain the slight misalignment of the type-B Fe NWs. The I-V characteristic of a single type-B Fe NW measured at room temperature displays a straight line nature corresponding to a resistivity of about 2.3 × 10~(-7) Ωm.
