Verfahren zur Herstellung einer Mikrostruktur und eines mit der Mikrostruktur versehenen Substrats

摘要

A method is provided for manufacturing a microstructure on a substrate in which the substrate has thereon linear and parallel atomic steps. The microstructure includes linear elements that extend along the atomic steps. The method includes a step for preparing a substrate having atomic steps on its surface and a step for applying linear elements onto the substrate. Each linear element is oriented to extend along one of the atomic steps, with the result that a microstructure in which the linear elements extend along the atomic steps is formed on the substrate. The substrate can be prepared by subjecting a silicon carbide substrate, a sapphire substrate, or a zinc oxide substrate to an ultrasmoothing process. As the linear elements, peptide fibers can be employed that are made up of peptide molecules that formβ-sheet structures.
