We fabricate a rutile-rich TiO2 nanocrystalline layer by the sol–gel method on an epitaxial p-InGaN layer and characterize their conduction band offsets by photocurrent spectroscopy. The conduction band edge of p-In0.12Ga0.88N is higher in energy than that of the TiO2 nanocrystalline layer. The excitation of the TiO2/p-In0.12Ga0.88N electrode by 405 nm light causes a cathodic photocurrent and an increase in scattering light intensity owing to the hydrogen bubble formation on the electrode surface. These results indicate electron injection from the TiO2/p-InGaN electrode to the electrolyte and the possibility of hydrogen generation using visible light by TiO2/p-InGaN electrode.
