- Abstract
- Flexible organic bistable devices (OBDs) consisting of [6,6]-phenyl-C85 butyric acid methyl ester ([84]PCBM) blended with a polymethyl methacrylate (PMMA) layer were fabricated on indiumt-in-oxide (ITO) coated polyethylene terephthalate (PET) substrates. Current-voltage curves of the Al/[84] PCBM:PMMA/ITO/PET device at 300K showed a current bistability. The maximum ON/OFF ratios of the OBDs at flat and bent conditions were about 7.5 x 10(2) and 2.7 x 10(3), respectively. The cycle endurance was larger than 1 x 10(5) cycles. The memory mechanisms of the OBDs were attributed to trapping and detrapping processes of electrons into and from the PCBM clusters.
