Lithium cobalt oxide nanobatteries offer exciting prospects in the field of nonvolatile memories and neuromorphic circuits. However, the precise underlying resistive switching (RS) mechanism remains a matter of debate in two‐terminal cells. Herein, intriguing results, obtained by secondary ion mass spectroscopy (SIMS) 3D imaging, clearly demonstrate that the RS mechanism corresponds to lithium migration...
Both surface photovoltage and photocurrent enable to assess the effect of visible light illumination on the electrical behavior of a solar cell. We report on photovoltage and photocurrent measurements with nanometer scale resolution performed on the cross section of an epitaxial crystalline silicon solar cell, using respectively Kelvin probe force microscopy and conducting probe atomic force microscopy...
A substantial resistive switching of LixCoO2 mixed‐conductor thin films is observed for the first time. The occurrence of possible bipolar switching in these oxide thin films is by current–voltage curves, investigated by conducting‐probe atomic force microscopy (CP‐AFM). The films are incorporated into an {Au/LixCoO2/p++Si} device and exhibit a significant resistive‐switching process involving a ratio...
