Nonvolatile switching devices fabricated with Donor-Acceptor Polymer System |
| 초록 |
The polymer with donor-acceptor system can play a role of charge trap sites in memory devices. We synthesized new polymers of poly(9-(4-vinylphenyl)carbazole)-b-poly(2-vinylpyridine) (PVPCz-b-P2VP) and poly(2-(N-carbazolyl)ethyl methacrylate) end-capped with fullerene (PCzMA-C60) consisting of electron donors as carbazole (PVPCz, PCzMA) and electron acceptors as pyridine and fullerene (P2VP, C60)by anionic polymerization. In case of poly(9-(4-vinylphenyl)carbazole)-b-poly(2-vinylpyridine) (PVPCz-b-P2VP), The devices based on donor-acceptor ratios system showing a lamellar structure of PVPCz59 block copolymer exhibited non-volatile memory performance. Especially, the polymer on high loaded C60(PCzMA-C60) has bipolar and unipolar non-volatile memory behaviors with excellent reliability, stable endurance, and long retention time. |
