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.
