Effect of Interdiffusion and Crystallization on Threshold Switching Characteristics of Nb/Nb₂O₅/Pt Memristors

Sodium-Controlled Interfacial Resistive Switching in Thin Film Niobium Oxide for Neuromorphic Applications

“…Niobium oxides are employed in commercialized Li-ion batteries, showcasing the versatility of this material in the orthorhombic phase for industrial and scalable use. Despite this, previous investigations of niobium oxides’ memristive properties have mainly focused on oxygen vacancy filamentary ,− and threshold switching functionality − without demonstrating evidence for synaptic plasticity. There have been reports of Li + filamentary-based switching in LiNbO 3 , − but the neuromorphic properties or electrical robustness of these processes remain uncharacterized, despite reported intercalation dynamics of Li-ions. , …”
