The nanoscale electro-reduction in a memristive oxide is a highly relevant field for future non-volatile memory materials. Photoemission electron microscopy is used to identify the conducting filaments and correlate them to structural features of the top electrode that indicate a critical role of the three phase boundary (electrode-oxide-ambient) for the electro-chemical reduction. Based on simulated temperature profiles, the essential role of Joule heating through localized currents for electro-reduction and morphology changes is demonstrated. |
