First Demonstration of a Fully-Printed Mos2Rram on Flexible Substrate with Ultra-Low Switching Voltage and its Application as Electronic Synapse

Abstract

We demonstrate the first fully-printed resistive random access memory (RRAM) on flexible substrate using 2D layered dichalcogenides, exhibiting ultra-low switching voltage down to 0.18 V and an on/off ratio up to 107. The novel switching medium is printed by formulating multilayer molybdenum disulfide (MoS2) into 3D-printable ink. Both volatile and non-volatile resistive switching are achieved within a single device by varying current compliance, which enables the implementation of electronic synapse with neuromorphic functionality including short-term plasticity (STP) and long-term plasticity (LTP).
