Abstract

Anodic Aluminum Oxide (AAO) from thin film aluminum sputtered on silicon substrate was synthesized using the two-step anodization process using oxalic acid solution. Both the pore diameter and interpore spacing increases with increasing applied voltage. Least deviation for these parameters was noted at 40 V while a temperature of 5°C of the anodizing solution showed the smallest deviation for interpore spacing. Scanning electron microscope (SEM) was used to image the surface morphology of AAO at different parameters.
