- Abstract
- Organic bistable devices (OBDs) with a poly(methylmethacrylate) (PMMA)/poly(3-hexylthiophene) (P3HT) hybrid layer, acting as a charge storage region, formed by using a vertical phase self-separation method were fabricated. The current-voltage curves of the All P3HT/PMMA/indium-tin-oxide devices exhibited current bistabilities with a maximum ON/OFF ratio of 1 x 10(4). The write-read-erase-read sequence results demonstrated the switching characteristics of the OBDs. The cycling endurance number of the ON/OFF switching for the OBD was above 1 x 10(5). The memory characteristics of the OBDs were attributed to trapping and detrapping processes of electrons into and out of the P3HT/PMMA heterointerfaces.
