Fabrication of Functional Devices Based on Highly Ordered Anodic Porous Alumina

Abstract

Two types of preparation processes for highly ordered hole array structures of anodic porous alumina are described. In the naturally occurring ordering, long-range ordered hole configuration was obtained under appropriate anodization conditions. The pretexturing process using a mold yielded ideally ordered hole configuration with a single domain structure over the sample. Obtained highly ordered anodic porous alumina membranes were applied to preparation of several types of functional nanodevices. In addition, replication processes using highly ordered anodic porous alumina as a starting structure are described. Highly ordered metal and semiconductor hole arrays prepared by the replication processes were applied to the preparation of several types of functional electrodes.
