Negative Differential Resistance and Memory Effects in Organic Diodes
We observed a negative differential resistance (NDR) in organic diodes consisting of organic molecules sandwiched between Ag and ITO electrodes. The large NDR shown in current-voltage characteristics is reproducible, resulting in that the organic devices can be electrically switched between a high conductance state (ON state) and a low conductance state (OFF state), and different negative voltages produce different conductance currents, resulting in the single-level and multilevel memory capability of the devices. It can be found that the currents at both ON to OFF states are space-charge-limited , and attributed to the electron traps at the Ag/organic interface. The large and reproducible NDR makes the devices tremendous potential in low power memory and logic circuits.
