Structural diagram of AAO: Ordered porous layer in the upper part and aluminum support in the lower part

 

     The AAO portion in the single-pass film with cellular structure comprises a number of hexagonal column primitive cells (units) of oxide, and there is a circular hole in the middle of each of such units. A hemispherical barrier layer is situated between the oxide layer and metal in the lower end of the hole.
