The Nano-Femto Lab Group
STM image of the basal plane of graphite, measured under ambient conditions. Image dimensions: 2 nm X 3 nm. The group of Prof. Federico Rosei, NFL, studies the properties of nanostructured materials. Whenever we shrink materials down to nanoscale dimensions, new and unexpected phenomena are likely to appear. For example, think about gold (Au). In its bulk form, it is well known that Au is yellow, it is a good conductor and chemically inert. And yet, when reduced to the size of nanoscale clusters, Au powders appear to be red (in fact, they have been used to stain glass since medieval times), they are semiconducting and become chemically reactive (e.g. Au nanoclusters catalyze the oxidation of C monoxide). Thus, with respect to its bulk counterpart, nanogold changes its optical, electronic and chemical properties.
