PURPOSE: Mono crystalline iron germanide-based nano-wire and a method for manufacturing the same are provided to improve purity and prevent the generation of crystalline defects using a vapor-phase transporting process without a catalyst. CONSTITUTION: Mono crystalline iron germanide-based nano-wire is manufactured on a substrate by thermally vaporizing precursors containing germanium and iron halide. The nano-wire is formed into a hexagonal structure, and the aspect ratio of the nano-wire is between 20 and 300. A method for manufacturing the nano-wire includes the following: A first precursor and a second precursor are prepared and are thermally processed under inert gas atmosphere. The first precursor is arranged at the front side of a reaction furnace and contains iron halide. The second precursor is arranged at the rear side of the reaction furnace and contains germanium and carbon.
