Abstract

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.
