We studied the photoelectrochemical properties of p-type GaN compared with those of n-type GaN. Band-edge potentials of p-type GaN were determined from the Mott-Schottky plot, and we clarified the potentials to be identical to those of n-type GaN. Photocurrent in p-type GaN shows its potential as an electrode for photoelectrolysis of water.
