    Chemical Vapour Deposition system used for growth of Indium oxide nanostructures. Hydrogen doped nanostructures can also synthesized. Details of parts attached in system are below:
    1. Single zone tube furnace heated up to 1100 ᵒC .
    2. Mass flow controller for Ar gas which can control flow rate from 0 to 500sccm.
    3. A reservoir at upstream direction of gas flow, for mixing particular ambient like water, ethanol etc. vapours with Ar gas during growth. Heating mantle is used for adjusting temperature of ambient.
