image: Optical microscope images of complex nano-architectures based on silicon particles (magnification 100X, dark field). These structures are obtained via solid-state dewetting of an ultra-thin, flat layer of silicon on silicon dioxide. Before dewetting the thin film was patterned with simple shapes in order to guide the self-assembly of the complex nano-architectures. This material relates to a paper that appeared in the 10 Nov. 2017, issue of Science Advances, published by AAAS. The paper, by M. Naffouti at Université de Toulon in Marseille, France, and colleagues was titled, "Complex dewetting scenarios of ultrathin silicon films for large-scale nanoarchitectures." view more
