Bipolar and Unipolar Switching Characteristics of Nonvolatile Memory Device Fabricated with a Novel Polymer Bearing Carbazole and Fullerene Moieties |
| 초록 |
We report devices made of a nanoscale thin film of poly(2-(N-carbazolyl)ethyl methacrylate) end-capped with fullerene (PCzMA-C60) sandwiched between aluminum and indium-tin-oxide electrodes and their electrically bistable memory characteristics. The devices were easily fabricated via a simple conventional coating process of the polymer in solution, and found to exhibit programmable, rewritable nonvolatile memory characteristics with a high ON/OFF current ratio of up to 104, a long retention time in both ON and OFF states, and low power consumption. Furthermore, the devices revealed unipolar switching behavior as well as bipolar switching behavior, depending on the control of current compliance. The advantageous properties and ease of fabrication of the PCzMA-C60 based devices open up the possibility of the mass production of high performance digital nonvolatile polymer memory devices at low cost. |
