3D simulations of ordered nanopore growth in alumina

Anodization is an inexpensive and simple method for obtaining oxide layers on metals. When performed in certain parameter regimes these layers are nanostructured and can be used as scaffolds in manufacturing nanodevices. There is much dispute in the scientific community concerning the mechanism of anodization. Two models are most prominently featured in literature: Field Assisted Flow and Field Assisted Dissolution. We present a cellular automata implementation of the Field Assisted Dissolution model of anodization. In our work we provide evidence that this model yields the predicted hexagonally ordered porous layers that is in qualitative agreement with experimental work.
