Carbonaceous submicron sized islands: A surface patterning route to hierarchical macro/mesoporous thin films

A simple patterning method is presented, using dewetting as a surface exotemplate generating technique, to produce disk-like features of micron to submicron size. The localization of the templates is such that a large area of the substrate is covered when compared with other techniques like colloida...
