One-Dimensional Zn-Doped In2O3−SnO2 Superlattice Nanostructures

Abstract

One-dimensional (1D) Zn-doped In2O3−SnO2 superlattice nanostructures have been fabricated on single-crystal silicon substrates by the layer-by-layer growth mode via the thermal chemical vapor transport and condensation with Au catalysts. The morphology, structure, and composition of the as-synthesized 1D superlattice were analyzed in detail. To exploit the potential applications of the fabricated nanostructures, the field emission properties of samples were characterized. The growth mechanism of the 1D Zn-doped In2O3−SnO2 superlattice nanostructures was discussed on the basis of the vapor−liquid−solid process.
