Abstract
Official abstract text for this publication.
A photochemical electrode includes: an electrically-conductive layer; and a photo-excited material layer including a photo-excited material provided over the electrically-conductive layer, wherein in a surface of the photo-excited material layer, a lattice plane having highest atomic density in a crystal structure of the photo-excited material is oriented in a surface direction of the surface of the photo-excited material layer.
First claim
Opening claim text (preview).
What is claimed is: 1 . A photochemical electrode comprising: an electrically-conductive layer; and a photo-excited material layer including a photo-excited material provided over the electrically-conductive layer, wherein in a surface of the photo-excited material layer, a lattice plane having highest atomic density in a crystal structure of the photo-excited material is oriented in a surface direction of the surface of the photo-excited material layer. 2 . The photochemical electrode according to claim 1 , wherein the photo-excited material includes a wurtzite crystal structure, and the lattice plane is (0001) plane. 3 . The photochemical electrode according to claim 2 , wherein the photo-excited material including the wurtzite crystal structure is a solid solution of MN, M is at least any of gallium, aluminum, and indium, and zinc oxide. 4 . A method for generating a photochemical electrode, the method comprising: preparing an electrically-conductive layer that contains a metal or a metal oxide; spraying a photo-excited material onto the electrically-conductive layer and forming a layer; and annealing the electrically-conductive layer and the layer in a gas atmosphere. 5 . The method for generating the photochemical electrode according to claim 4 , wherein the photo-excited material is a gallium nitride-zinc oxide solid solution. 6 . The method for generating the photochemical electrode according to claim 4 , wherein the spraying is carried out by an aerosol-type nanoparticle deposition (NPD) method.
