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 of over four orders of magnitude.
