Porous Anodic Alumina: Self-Ordered Pore Growth

When aluminum is anodized in an acidic electrolyte, the growing oxide layer self-organizes into a hexagonal array of parallel nanopores rather than a flat film. This simulation renders that array as a 3D lattice of oxide cells, each with a central pore channel and a scalloped barrier layer at its base, and grows it over simulated anodizing time. Adjust the applied voltage, electrolyte and current density to see how the interpore distance, pore diameter, barrier-layer thickness and porosity respond, and watch the lattice snap from a regular hexagonal pattern into a disordered, branched one outside each electrolyte's narrow self-ordering voltage window — the same window process engineers target when growing real AAO templates.
