摘要
We fabricated an 8 x 8 cross-bar array-type organic nonvolatile memory devices on twistable poly(ethylene terephthalate) (PET) substrate. A composite of polyimide (PI) and 6-phenyl-C61 butyric acid methyl ester (PCBM) was used as the active material for the memory devices. The organic memory devices showed a high ON/OFF current ratio, reproducibility with good endurance cycle, and stability with long retention time over 5 x 10(4) s on the flat substrate. The device performance remained well under the twisted condition with a twist angle up to similar to 30 degrees. The twistable organic memory device has a potential to be utilized in more complex flexible organic device configurations. (C) 2013 Elsevier B.V. All rights reserved.
