Growth of CrO[subscript 2] coated single crystalline (SnO[subscript 2]) tin oxide nanowires

Abstract

Single crystalline tin oxide (SnO[subscript 2]) nanowires have been synthesized by carbothermal reduction of SnO[subscript 2] 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 TiO[subscript 2] substrates of orientations of (100) and (110) that are coated with a thin film and colloids of gold (Au) catalyst. After the SnO[subscript 2] nanowire growth on TiO[subscript 2] substrates, the substrates were put inside the another chemical vapor deposition (CVD) system to coat CrO[subscript 2] on the nanowires. CrO[subscript 2] coating success on SnO[subscript 2] nanowires were discussed.
