Abstract

Indium Oxide is an important transparent conducting oxide that has drawn attention owing to its high transparency in the visible region and good electrical conductivity. These properties make IO suitable for many technological applications such as solar cell, heat mirror, transparent conducting electrodes and light emitting devices. The morphology dependent properties of IO nanostructures have been observed in IO pyramid-based field emission devices, IO nanowire-based chemical sensors, vertical Field Emission Transitors, multi-level memory devices and nanotube based toxic gas detectors. To realize all this, a basic understanding of growth mechanism of Indium Oxide is a prime requirement. In the present work, a simple thermal CVD) technique has been utilized for the synthesis of different IO nanostructures and the characterization of the nanostructures has been done using SEM, TEM and GAXRD. In the first part, effect of varying different experimental parameters on the morphology of the nanostructure obtained is studied. By understanding the nature of the deposition with respect to different parameters, we've found out the optimum parameters for deposition and made some interesting observations, keeping in mind the challenge of growing metal oxide heterojunctions. Electrical characterization of the Nanowire and Nanorods film has been done by sheet resistance measurement. The major focus of the work is on the growth of novel nanostructure and the formulation of their growth mechanisms and simultaneously envisioning their use for future device applications viz, the growth of Polyhedral Indium Zinc Oxide Microcontainers and the growth under strongly reducing hydrazine ambient. The work has been centred on Indium Zinc oxide nanocomposite structures and heterojunctions.
