Figure 2From: Fast anodization fabrication of AAO and barrier perforation process on ITO glassSchematic diagram illustrating the pore formation mechanism in anodic alumina. (a) Original aluminum sputtered on ITO glass; (b) the pore progress through the aluminum film and their tending towards an ordered hexagonal arrangement; (c) barrier layer reaching the substrate, (d) fully formed AAO film with barrier layer; and (e) the disappearance of the barrier layer.Back to article page
