Abstract

original image

Ion nanowire: Electron transport through discrete gold-ion arrays within coordination cages was directly measured between Au nanogap electrodes (see picture) using STM. Precise calibration of the electron transport distance demonstrates that Au-ion arrays exhibit good conductance and only moderate loss with increasing transport length.
