Abstract

Indium-zinc oxide nanostructures, such as nanosheets, nanobelts, and wires formed by oriented stacks of nanoplates have been grown by a controlled thermal evaporation method without the use of a foreign catalyst. Surface features in the stacked hexagonal nanoplates suggest a dislocation-driven growth mechanism for these structures. A growth model for these stacks is proposed based on changes in velocity growth rate between the outer and the inner part of the plates. Zn incorporation has been investigated by means of energy-dispersive spectroscopy, X-ray photoelectron spectroscopy, and selected area electron diffraction. The formation of Zn_k In_2O_(k+3) ternary compounds has been demonstrated. Cathodoluminescence emission and its correlation with the morphology of the structures and Zn content have been studied.
