Schottky barrier heights of Ni, Pt, Pd, and Au on n-type GaN were measured using current-voltage and capacitance-voltage techniques. Measurements from the I-V technique yielded barrier heights of 0.95, 1.01, 0.94, and 0.87 eV for Ni, Pt, Pd, and Au, respectively. Barrier heights of 1.13,1.16, 1.07, and 0.98 eV, for Ni, Pt, Pd, and Au, respectively, were obtained using C-V measurements.
