Abstract :
In this letter, we investigated the current-dependent switching characteristics of Al/6F-HAB-diphenyl carbamyl (PI-DPC)/Al devices fabricated by spin coating. The current required to switch off the device increased with an increase in the current compliance, limiting the on-state current, whereas the on and off voltages were almost constant. In addition, the turn-off current and the on and off voltages remained almost constant at the constant current compliance. The observed phenomenon indicates that the bistability of the PI-DPC device that is induced by controlling the current is attributed to filament formation and repulsive Coulomb interaction by charge trapping.
