Abstract:
A nanogroove-striped pattern was formed on a NiO film surface. The periodic nanopattern was successfully obtained over the entire surface via high-temperature annealing of the epitaxial NiO thin film, which was grown on an atomically stepped sapphire substrate at low temperature. The depth, width and interval of straight nanogrooves were about 3 nm, 35 nm and about 100 nm, respectively. The periodicity of the stripe agrees well with that of the atomic steps of the substrate.
