Abstract

Indium Oxide was successfully grown via direct thermal oxidation of Au-coated In films on glass substrates. The XRD spectra obtained from the oxidized samples show complete oxidation of the as-deposited AuIn layers. The SEM images reveal island formation rather smooth films of deposited AuIn metal layers. Truncated tetrahedrons, cut tetrahedrons, and octahedrons structures were formed at the surface of the oxidized samples while nanoarrows were grown along the edges. By increasing the thickness of the In source layer the diameter and length of the nanoarrows also increases. It was found out that increasing the thickness of the Au catalyst layer does not present any trend to the sizes of the grown nanoarrows. Substrate texturing can promote 1D growth even along the surface of the sample.
