Highly Ordered Nanoscale Patterns on Anodic Aluminum Oxide (AAO) Surface

摘要

The surface morphology of the anodic aluminum oxide (AAO) prepared with different surface coating has been studied by AFM and SEM. Under optimized condition, highly ordered stripe patterns have been obtained. These regular patterns, including random stripes and regular stripes, show strong dependence on the crystal orientation of the aluminum substrate. This method can be developed into a novel nanoscale fabrication technique.
