Abstract :
In this letter, the conduction mechanism in nanoparticle-contained polymer memory was investigated experimentally and theoretically. The current-voltage characteristics showed that the device switches from an initial low-conductivity state to a high-conductivity state upon application of an external electric field at room temperature. The current transition exhibited a very narrow voltage range that causes an abrupt increase of current. A trap-filled space-charge-limited current model was proposed and supported by the experimental data to explain the transport mechanism in organic memory.
