Electrical Bistability Mechanisms of Organic Bistable Devices Fabricated Utilizing Ni_(1-x)Fe_x Self-Assembled Nanoparticles Embedded in a Polyimide Layer

摘要

Current-voltage (I-V) measurements on Al/Ni_(1-x)Fe_x nanoparticles embedded in polyimide/Al devices at 300 K showed a current bistability due to the existence of Ni_(1-x)Fe_x nanoparticles. The ON/OFF current ratio for the fabricated devices was about 10~2. The retention time data of the devices demonstrated charge trapping and detrapping processes. Carrier transport mechanisms of the devices are described on the basis of the I-V experimental and fitting results.
