| Abstract(in English) | Filamentary conductive paths (filaments) formed in Pt/NiO/Pt cells have been directly observed by Conductive-AFM. After forming process, deformations on the surface of NiO thin films are observed. The deformations have been confirmed to be protrusions or depressions with the diameter of about 1μm. It is revealed that from several to more than ten filaments are preferentially distributed along the edge of a deformation. The area of a filament is typically 2500 nm^2, ranging approximately from 200 nm^2 to 20000 nm^2. In low-resistance state, current through the cells is dominated by the filaments with the resistivity of the order of 10mΩcm. It is also suggested that the variation of the resistance in low-resistance state originate from the changes in the area as well as the shape of the filaments. |
