A very simple and inexpensive method for growing β-Ga2O3 films by heating GaAs wafers at high temperature in a furnace was found to contribute to large-area, high-quality β-Ga2O3 nanoscale thin films as well as nanowires depending on the growth conditions. We present the material characterization results including the optical band gap, Schottky barrier height with metal (gold), field ionization and photoconductance of β-Ga2O3 film and nanowires.
