Abstract: Vapour-Liquid-Solid (VLS) mechanism is employed to grow Ga2O3 and In2O3 nanowires (NWs) using Ga2O3:C, In2O3:C and metallic In as precursor materials. A first attempt to fabricate heterostructures of Ga2O3/In2O3 NWs is also presented, by growing In2O3 NWs on previously grown Ga2O3 NWs. The NWs have been structurally characterized with Scanning Electron Microscopy and X-Ray diffraction. Moreover, gas sensors based on individual Ga2O3 NWs have been fabricated and tested under different concentrations of relative humidity diluted in synthetic air, demonstrating effectiveness in gas sensing
