      abstract     = {The discrete and charge-separated nature of matter -
                      electrons and nuclei - results in local electrostatic fields
                      that are ubiquitous in nanoscale structures and are
                      determined by their shape, material, and environment. Such
                      fields are relevant in catalysis, nanoelectronics and
                      quantum nanoscience, and their control will become even more
                      important as the devices in question reach few-nanometres
                      dimensions. Surface-averaging techniques provide only
                      limited experimental access to these potentials at and
                      around individual nanostructures. Here, we use scanning
                      quantum dot microscopy to investigate how electric
                      potentials evolve as nanostructures are built up atom by
                      atom. We image the potential over adatoms, chains, and
                      clusters of Ag and Au atoms on Ag(111) and quantify their
                      surface dipole moments. By focusing on the total charge
                      density, these data establish a new benchmark for ab initio
                      calculations. Indeed, our density functional theory
                      calculations not only show an impressive agreement with
                      experiment, but also allow a deeper analysis of the
                      mechanisms behind the dipole formation, their dependence on
                      fundamental atomic properties and on the atomic
                      configuration of the nanostructures. This allows us to
                      formulate an intuitive picture of the basic mechanisms
                      behind dipole formation, which enables better design choices
                      for future nanoscale systems such as single atom catalysts.},
