Abstract

Anodic Aluminum Oxide (AAO) was synthesized by anodizing thin film aluminum, with thickness of approximately 200nm, deposited on a silicon substrate via RF magnetron sputtering. Two-step anodization process using 0.3 Molar oxalic acid solution at applied potential of 40 volts was able to show high nanopore density and nearly ordered nanopore arrangement. Etching time with 5% phosphoric acid was varied in order to control nanopore diameter. The morphologic and physical characterizations of the alumina film samples were carried out by Scanning Electron Microscope (SEM).
