Bulk-quantity synthesis and self-catalytic VLS growth of SnO ₂ nanowires by lower-temperature evaporation

• 摘要：

  Tin oxide (SnO ₂ ) nanowires have been synthesized in bulk quantities at lower temperature (680 °C) by thermal evaporation of SnO powder. These as-synthesized SnO ₂ nanowires are single crystals with [3 0 1] growth axis, with diameters ranging from 10 to 190 nm and lengths extending to tens of micrometers. The growth of SnO ₂ nanowires synthesized by lower-temperature evaporation is dominated by a self-catalytic vapor-liquid-solid (VLS) mechanism. The self-catalytic effect in VLS process has been described.
