There has been a great interest in metal oxides nanostructures (such as ZnO, SnO2, etc.,) recently. Metal oxides have many potential applications in sensing, optoelectronics, field emission and piezoelectricity. In addition, metal oxides nanomaterial features various morphologies such as nanowire, nanorod, nanocomb, nanopencil, nanopin, nanobelt, nanospring, etc., which indicate different functions in diversified devices. This reports aims to investigate growing metal oxides nanostructures by vapor phase transport method and study the growth mechanism and morphology dependence on different growth parameters such as temperature, pressure and gas flow rates. And in the later part, some devices such as light-emitting diodes based on the metal oxides nanostructure materials will be fabricated and characterized.
