| Formation of highly ordered nanostructures on Al (100), (110) and (111) single crystals was studied for anodic pore growth and electropolishing. Electropolishing produced self-ordered shallow, height 2-7 nm, nanotopographies, which were different for different crystalline faces at the same electropolishing conditions; 40-65 nm periodic stripes on Al (110), and hexagonal mounds on Al (100) and Al (111). For Al (110) regular stripes extended over the whole sample area, about 1 cm2, demonstrating that this face is a promising template for sputtering. Anodic pore growth using modified multi-cycle Masuda process produced self-ordered pores at the same rate for all faces. The highest ordered domain area, about 100 µm2, was achieved on Al (100) face. |
