In this chapter, the synthesis and applications of highly ordered anodic porous
alumina have been described. Highly ordered anodic porous alumina was prepared
based on the naturally occurring self-ordering and pretexturing processes
of Al. The obtained anodic porous alumina with highly ordered pore arrangement
could be applied, for example, to the fabrication of several types of ordered metal
and semiconductor nanostructures, nanocomposite, nanodots array, and nanohole
array.
The highly ordered anodic porous alumina will be applicable to the preparation
of a wide variety of functional nanodevices because of its unique fine geometrical
structures that are easily controlled by adjusting the anodizing conditions.
