Growth And Characterization Of ZnO Nanostructures By A Self-Catalythic CVD Process

Abstract

In the last years, many papers have dealt with the topic of metal oxide nanowire growth and characterization. In particular, it is widely reported that Zinc Oxide (ZnO) can be obtained in a large variety of nanostructures with different morphologies, namely nanowires, nanorods, nanotetrapods (or simply "tetrapods"), nanotapes or nanoribbons, etc. The possibility to obtain this material in different nanosized crystalline structures is particularly interesting in view of several application fields, e.g. chemical sensors, solar-cells, optoelectronics. However, different nanostructures often appear mixed on the same substrate, thus limiting the possibility of exploitation for applications
