This project is an approach towards the synthesis and characterization of liquid Gallium filled Indium Oxide nanothermometer by using resistive chemical vapor deposition technique. All the measurements and microscopical studies has been presented by using the concepts of different microscopies like XRD/SEM/EDX/HRTEM and related sample characterization software like Pcpdfwin (XRD-Analysis), Origin (Plotting graphs), Image Tool (SEM Images Analysis) and Digital Micrograph (TEM/HRTEM Images Analysis). The growth methods such as resistive heating chemical vapor deposition (RH-CVD) and growth mechanisms such as vapor-liquid-solid (VLS) and vapor solid (VS) of growing nanotubular structures have been discussed in this report. The HRTEM-EDX measurement along the radial direction of an Indium Oxide nanotubular structure explore the in depth knowledge of the flow of liquid Gallium. These similar observations have not been reported by other authors. The synthesis of metal filled Oxide nanotubular structures may have potential applications in future nanofluid devices. It could be ideal for the semiconductor industry and bio medical fields.
