Claim Text:
1. A method for manufacturing a nanowire comprising: providing a silicon source gas in a chamber; controlling the temperature of a substrate received in the chamber separately from the temperature of the source gas, the substrate being formed of a material selected from the group consisting of silicon (Si), glass, quartz, indium-tin oxide (ITO), alumina (Al203), and stainless steel (SUS); heating the chamber using a heat source that surrounds the chamber both above and below the substrate; cooling the substrate to form a temperature gradient on the substrate perpendicular to the substrate, wherein the substrate is cooled by providing a cooling medium to indirectly contact a susceptor that is located in a lower portion of the substrate for supporting the substrate; and forming a silicon nanowire directly on the substrate, the silicon nanowire being grown in a direction perpendicular to the substrate and having at least one growth condition selected from the group consisting of growth speed and growth direction controlled according to the temperature gradient on the substrate.
