Total structure of Ag374 nanoparticle and its appearance in STM imaging. a, b Complete cluster structure shown in a plane perpendicular to a five-fold rotation axis and a plane parallel to the five-fold axis, respectively (from ref.21, copyright 2016 SpringerNature). c STM topography image of Ag374 at LHe temperature. Scan size: 25.1 × 25.1 nm2, bias and setpoint current: 1.2 V and 30 pA. Blue dashed circles indicate nanoclusters with a defined size (diameter 5 nm) and their locations. d Height profiles taken along the red and black lines in c
