Visualizing Local Doping Effects of Individual Water Clusters on Gold(111)-Supported Graphene

The local charge carrier density of graphene can exhibit significant and highly localized variations that arise from the interaction between graphene and the local environment, such as adsorbed water, or a supporting substrate. However, it has been difficult to correlate such spatial variations with...
