/W ECM memristors. Contrary to the traditional ECM theory, the CFs are found to grow from the anode to the cathode and dissolve from the cathode to the anode. Notably, Ag CFs with different crystal structures and metallic sulfide-type CFs are observed in the memristors. These results provide deeper insights into the RS mechanism in 2D material-based ECM memristors and facilitate the optimization of memristive devices.
