Abstract
Gold clusters and individual atoms are seen on few-layer graphene in the scanning transmission electron microscopy high-angle annular dark-field (STEM-HAADF) image and individual atom positions are determined by the corresponding STEM bright-field image. The clusters nucleate exclusively in the hydrocarbon surface contamination. HAADF imaging is one of the most feasible methods to detect individual adatoms and impurities.
