摘要Abstract: The effects of porous underlayers on the photocurrents of N-doped TiO2 films were investigated. The
porous underlayers were prepared by glancing angle deposition (GLAD) on irregular arrays of copper and nickel
nanoparticles on ITO glass substrates. The N-doped TiO2 films were grown by atomic layer deposition. The
morphologies and porosity of underlayers were characterized by a scanning electron microscopy. The
photocurrent response properties of N-doped TiO2 films were examined in a wet-type three-electrode cell using a
potentiostat system. The results show that the photocurrent response of N-doped TiO2 films in visible light was
improved by the GLAD porous underlayers.
