Self-assembled arrays of ZnO stripes by anodization

In this work we investigate the fabrication of self-assembled stripe arrays of zinc oxides by anodization of Zn in ethanolic H2SO4. H2O-selective dissolution of ZnO and flow of H2O by convection are attributed to the formation of the self-controlled stripes. The stripes consist of ZnO with morphology of polygonal flakes perpendicular to the surface. Effects of H2SO4 concentration, applied potential, and anodizing time on the formation of stripes will be discussed in detail.
