Improved fabrication efficiency of nanoporous alumina templates for nanostructure growt

Resumo

A process to achieve alumina film cathodic delamination produced by hard anodization was developed during this work, opening the possibility to investigate the phenomena involved during the film delamination. The obtained free-standing films exhibits adequate structural and chemical characteristics. While the pore surface is being cleaned and polished during the cathodic etching process, it also ensures the formation of ?-Al2O3, the most stable phase of aluminum hydroxide.
