A researcher who coauthored measurements of chemical bonding around individual impurity atoms in graphene. Scanning transmission electron microscopy located silicon impurities, while electron energy loss spectroscopy probed their electronic environment. Comparing differently coordinated sites with calculations connected an atom's visible position to its bonding, extending microscopy beyond identifying where the atoms are.[ref]
Direct Determination of the Chemical Bonding of Individual Impurities in Graphene by Wu Zhou and others. Abstract: atomic imaging, energy-loss spectra and threefold versus fourfold silicon coordination
