We report the current-voltage-temperature characteristics of Au/Ni/n-Al0.35Ga0.65N Schottky contacts measured over a wide temperature range. For larger forward bias, the current-voltage characteristics were well described by the thermionic emission model. By means of curve fitting, we could determine the relative contribution of the conduction mechanisms at each temperature.
