Enhanced Switching in Solid Polymer Electrolyte Memristor Devices via the addition of Interfacial Barriers and Quantum Dots

Gater, Michael; Adawi, Ali; Kemp, Neil

Abstract

We report on the electrical effects of single and double polymer (polymethacrylate) barriers on polyethylene oxide (PEO) based memristors. The single barrier device with an active layer embedded with WS2 quantum dots is also investigated. The addition of a single PMA barrier yields multi cross point current-voltage hysteresis while the addition of embedded quantum dots removes multi-cross point behavior and shows repeatable uni-polar switching with the device starting in the low resistive state (LRS). The device shows some capability of reversible unipolar to bipolar operation as a function of applied voltage and device rest time. The addition of a double PMA barrier produces a reproducible unipolar switching behavior and a unipolar negative differential resistance behavior at higher voltage operation.
