Surface Patterning using Nano-Templates For Realizing Highly Ordered Nanostructure Arrays with Controllable Properties — •Huaping Zhao, Shikuan Yang, Fabian Grote, Feng Xu, and Yong Lei — Institute of Materials Physics and Center for Nanotechnology, University of Muenster, Muenster 48149, Germany

Here we present the research progress of template-based surface nano-patterning techniques [1-5] in our group. Two kinds of templates were used in the surface patterning process: ultra-thin alumina membranes and monolayer polystyrene spheres. Using the templates, surface patterns of different materials with diverse shapes were synthesized. The structural parameters of the template-prepared surface patterns largely depend on those of the templates. The feature size of the building blocks of the patterns can be adjusted from the quantum size to nanoscale and microscale range [1]. The cost-effective and time-saving fabrication processes of template-based surface patterning approaches are highly desirable for industrial applications in fabricating different nano-devices, giving rise to broad applications of template-prepared surface nanostructures.
