Influence of Top Electrode Metal on Resistive Switching in Multilayer MOCVD MoS2 Memristors
Advanced Electronic Materials, EarlyView.MoS2 memristors typically use evaporated noble metal electrodes. This study compares Pd, Ni, and Al electrodes and sputtered versus evaporated deposition. Pd is passive, while Ni damages MoS2, yielding poor switching. Sputtered Al enables reproducible ECM‐type switching with 95% yield, whereas evaporated Al forms an interfacial oxide that suppresses ...
