Figure 1From: Epitaxial deposition of silver ultra-fine nano-clusters on defect-free surfaces of HOPG-derived few-layer graphene in a UHV multi-chamber by in situ STM, ex situ XPS, and ab initio calculationsSTM images of Ag clusters. (a) STM images (3 mV, 2 nA) of Ag clusters deposited onto a HOPG substrate illustrating the Volmer-Weber cluster growth, (b) line scan taken along the white line in (a). The graphs in (c) and (d) are histograms of particle height and particle diameter distributions, respectively.Back to article page
