Organic synaptic devices based on ionic gel with reduced leakage current

Abstract

In this work, we presented a solid-state hybrid electrolyte dielectric film fabricated by a facile solution process, composed of ionic liquid and high-k polymers for leakage current reduction. With ions involved in the dielectric, the organic transistor can be operated under low voltage, and some essential synaptic behaviors were successfully simulated by the electrostatic coupling effect for building neuromorphic computing systems.
