Abstract

Single crystalline tin oxide (SnO₂) nanowires have been synthesized by carbothermal reduction of SnO₂ nanopowder followed by thermal evaporation of the reduced precursor and growth via the vapor-liquid-solid (VLS) growth mechanism. The nanowires are deposited on single crystalline TiO₂ substrates of orientations of (100) and (110) that are coated with a thin film and colloids of gold (Au) catalyst. After the SnO₂ nanowire growth on TiO₂ substrates, the substrates were put inside the another chemical vapor deposition (CVD) system to coat CrO₂ on the nanowires. CrO₂ coating success on SnO₂ nanowires were discussed.
