dc.description.abstract A three-step process has been developed for the fabrication of hybrid nanostructures consisting of Ga2O3 nanowires array decorated with gold nanodots, addressing the issue of noble metal functionalization of oxide nanowire networks with high resistance. The first step involves anodizing GaAs substrates to produce GaAs nanowires with high electrical conductivity. In the second step, gold nanodots are electrochemically deposited. The third step involves thermal treatment in an argon atmosphere with a small amount of oxygen, selectively converting GaAs nanowires into Ga2O3 nanowires covered with gold nanodots. The process is cost-efficient and accessible, and the resulting hybrid nanostructures exhibit promising properties for various applications in sensing, photodetection, and catalysis.
