Ultrathin AAO templates have self-organized honeycomb-like nanopores, and they are usually from several ten nanometers to several hundred nanometers in thickness.Ultrathin AAO templates have been widely used for fabrication of large-scale ordered arrays of surface nanostructures such as nanodots and nanoholes on the surface of substrates. Pores of ultrathin AAO template are uniform in diameter and highly ordered in a short-range. In addition, the material (Al2O3) is transparent in the near-infra...

AAO on Al substrate has honeycomb-like structure (shown in Fig. 1), composed with hexagon column of Al2O3, with a circular pore in the center. At the end of the pore, there is a half-sphere shape barrier layer oxide layer in contact with aluminum. The porous oxide film contains mutually parallel cylindrical pores extending from the barrier oxide layer to the film surface. AAO on Al substrate is the simplest product in AAO family, which can be fabricated into large area with a high success rate. ...

Using AAO as template, various one-dimensional nanomaterial arrays can be easily fabricated by electrochemical deposition. Generally, double-pass AAO templates are used. One layer of metal conductive layer is evaporated on the side of the template, and then nanomaterials are prepared by DC electrochemical deposition. However, double-pass AAO templates are fragile and inconvenient to operate. Evaporation of metal conductive layer also increases the cost and complexity of the experiment. If single...

In-situ fabrication of AAO templates on silicon wafers: (left) 2 inches, (right) 4 inches. The preparation of AAO template by using high purity aluminium sheet has the advantages of good uniformity and good operability. However, the AAO template prepared from high purity aluminium sheet is difficult to be compatible with semiconductor technology, and it is not easy to obtain more precise and controllable micro-structures and micro-devices. Moreover, the ultra-thin AAO template prepa...
