An experimental <physicist> who, with collaborators, used <scanning tunnelling microscopy> to image <standing waves> in the electronic <surface states> of copper. Steps and defects scattered the <two-dimensional electron gas>, producing spatial oscillations in the <local density of states>. Measuring those patterns gave access to the electrons' <dispersion relation>, making a quantum-wave property visible in a real-space experiment.<Imaging standing waves in a two-dimensional electron gas by M. F. Crommie and others>[Abstract: Cu(111), scattering from steps and point defects, and surface-state dispersion]{ref}
