Path-directed and maskless fabrication of ordered TiO2 nanoribbons

Highly ordered TiO(2) nanoribbons with a width from 150 nm to several micrometres and a thickness of 60 nm were fabricated by a path-directed and maskless route. Structural analysis and mechanical properties indicate that the nanoribbons are suited for constructing array-nanodevices. The method exhibits many advantages such as designability, precise size control and good transferability.
