NWs grown by reactive deposition epitaxy (RDE) on silicon (110) show dimensions of lOnmxSnm, and several micrometres in length. By using conductive-AFM (e-AFM), electron transport properties of one single NW is measured, resistivity of a single crystalline FeSi2 NW is estimated to be 225 μΩ.cm. Using superconducting quantum interference device (SQUID), we measure a magnetic moment of 0.3 ± 0.1 Bohr magneton per iron atom for these FeSi2 NWs.展开更多
We report the characterization of self-assembled epitaxially grown transition metal, Fe, Co, Ni, silicide nanowires (TM-NW) growth and electrical transport properties.

NWs grown by reactive deposition epitaxy on various silicon surfaces show a dimension of 10nm by 5nm, and several micrometers in length. NW orientations strongly depend on substrate crystal orientation, and follow the substrate symmetry. By using conductive-AFM (c-AFM), the electron transport properties of one single NW were measured, the resistivity of crystalline nickel silicide NW was estimated to be 2×10-2Ω・cm.展开更多
