Abstract

Surfaces are natural templates for the formation of periodic nanostructure arrays. Besides acting as a mere support for the individual nanoscale entities the structure of the supporting surface may or may not influence the lateral arrangements of the elements of the array as a whole.

The decisive parameters are the adsorbate-substrate- and the adsorbate-adsorbate-interaction as well as the magnitude of activation barriers. In this lecture examples for nanostructure formation will cover the spontaneous growth of periodic arrays of monodispers metal clusters, the formation of ordered organic layers at metal/electrolyte interfaces, and the self-organization of epicuticular wax sculptures from plant leaves.
