| 제목 | Resistive analog switching in Au/La₂O₃/Pt structure |
| 초록 | Analog-type resistive switching with sequentially changing resistance has attracted interest recently for applications such as analog nonvolatile memory, programmable analog circuits, and neuromorphic devices. Nanomaterials such as nanoparticles (NPs) films have been demonstrated to exhibit digital nonvolatile resistive switching and analog switching. The usage of nanoparticles has the advantage that the internal structure can be designed during the synthesis stage to assemble a stacked 2D plate structure. In this study, characteristics of square-shaped 2D La₂O₃ nanoparticles layer between Au and Pt electrodes were investigated. The current-voltage curves show hysteresis with decreasing resistance for repeating negative voltage sweeps and increasing resistance for repeating positive-voltage sweeps. furthermore, the analog switching with respect to the polarity of voltage is equivalent to adaptive synaptic motion of potentiation and depression of biological system. |
