Abstract：
The electrical properties of a nonvolatile organic bistable device (OBD) utilizing Au quantum dots (QDs) sandwiched between two thin insulating polyimide layers were investigated. Current- voltage (I-V) measurements on the device at room temperature showed a current bistability due to the existence of the Au QDs. The maximum ON/OFF ratio of the current bistability in the OBD was 1 x 10(8), the largest value ever reported for a stable OBD. The device has excellent endurance and retention ability in ambient conditions. The electrical properties and operating mechanisms for the device are analyzed on the basis of the I-V results.
