Programmable Digital Memory Behaviors of Functional Aromatic Polyimides Bearing Triphenylamine Derivatives: Effects of Electron Donor and Acceptor Substituents |
| 초록 |
A series of aromatic polyimides (PIs) were synthesized via the polymerization of 3,3′,4,4′-diphenylsulfonyltetracarboxylic dianhydride with 4,4′-diaminotriphenylamine derivatives containing hydrogen, cyano, methoxy, or dimethylamine substituents. Nanoscale thin films of the PIs demonstrated excellent electrical memory performance, with high stabilities and ON/OFF current ratios. The memory characteristics were found to be tunable by varying the substituents; nonvolatile WORM behavior, nonvolatile ON/OFF switching type memory behavior, and volatile DRAM behavior were observed. In addition, the film density was a significant factor influencing the observed memory behaviors. All of the memory behaviors were found to be governed by a mechanism involving trap-limited spacecharge-limited conduction and local filament formation. |
