Abstract: Nanoscale break junctions created through electromigration naturally produce arrays of individual gold nanoclusters spanning the electrodes. These spatially resolvable individual nanoclusters electroluminesce in response to pulsed external electric fields, producing a noncontroversial, corroborative readout of nanoscale charge injection. Modulation of the electrical pulse sequence timing, polarity, and amplitude reveals electroluminescence from discrete electronic energy levels and provides a measurement of the relative coupling between an emitting cluster and its individual electrodes.
