Abstract: "Ultralong beltlike (or
ribbonlike) nanostructures (so-called nanobelts) were successfully synthesized
for
semiconducting oxides of zinc, tin, indium, cadmium, and gallium by simply
evaporating the desired commercial metal
oxide powders at high temperatures. The as-synthesized oxide nanobelts are
pure, structurally uniform, and single
crystalline, and most of them are free from defects and dislocations. They
have a rectanglelike cross section with
typical widths of 30 to 300 nanometers, width-to-thickness ratios of 5 to10,
and lengths of up to a few millimeters.
The beltlike morphology appears to be a distinctive and common structural
characteristic for the family of semiconducting oxides with cations of
different valence states and materials of distinct crystallographic
structures. The nanobelts could be an ideal system for fully understanding
dimensionally confined transport phenomena in functional oxides and building
functional devices along individual nanobelts."
