Abstract
We report a pentacene-based bistable memory device using Fe as the top electrode and compare it to the Al/pentacene/Al devices. The device displays stable switching from the low-current OFF state to the high-current ON state and long retention time. Our results suggest that Fe has the advantage over Al as the top electrode because it lowers the switching threshold voltage. The Fe devices exhibit similar temperature-dependent behaviors with the reported Al/pentacene/Al devices [D. Tondelier, K. Lmimouni, D. Vuillaume, Appl. Phys. Lett. 85 (2004) 5763]. The device is promising as a write-once read-many (WORM) memory.
