Side Chains Contributions to the Characteristics of Resistive Memory based on Conjugated Polyelectrolytes |
| 초록 |
We investigate the effects of the structure and length of side chains on the characteristics of organic resistive memory devices with water-soluble polyfluorene (WPF) derivatives. The WPF derivatives have either an ethylene oxide (EO) or an alkyl side chain and are synthesized; the lengths of the EO side chains are 2, 4, or 6 molecules. The WPFs with the EO side chains show better memory characteristics than those with alkyl side chains of similar length. WPF-4O and WPF-hexyl show Vth values of 3 and 5 V and ON/OFF ratios of 102 and 105, respectively. The WPFs with longer EO side chains exhibit better memory characteristics than the WPF-2O with short EO side chain. The Vth values and ON/OFF ratios for WPF-2O, WPF-4O, and WPF-6O are 4, 3, and 3V, and 5 × 102, 105, and 105, respectively. The excellent switching properties of WPF-4O and WPF-6O are believed to be mainly attributed to the low trap density and highly localized current pathways. |
