Egg-White-Based Polymer Memristors With Competing Electronic-Ionic Effect and Timescale-Dependent Current Modulation

Polymer thin film memristors based on the egg-white dielectric are achieved through a simple solution process, showing the coexistence of the clockwise and counterclockwise current hysteresis in a single device. Such unique memristive feature originates from two competing effects in the egg-white dielectric that possess different effective time ranges. The ion redistribution and charge trapping effects are dominant over relatively short and long timescales, respectively. The reversible and timescale dependent memristive characteristics in the polymer memristors may offer a new strategy towards organic electronic synapses.
