A surfactant-free, template-less and seed-less method, namely the thermal-assisted photoreduction (TAP) process, has been developed to synthesize vertically grown Au nanowires (30-80 nm in diameter and about 2 μm in length) on the surface of thin film titanium dioxide (TiO2), which is locally excited by blackbody radiation. The Au nanowires thus produced are single-crystalline with a preferred growth direction. The electrical behavior investigated using a nanomanipulation device indicates that the Au nanowires possess an excellent electrical resistivity of about 3.49 × 10 -8 Ω m.
