Synaptic effect and non-volatile switching modulated by LiCoO2/boehmite composite layer

In this study, a memristor was modulated to exhibit both synaptic effects and non-volatile switching through the use of a composite layer made of LiCoO2 and boehmite. At low applied bias, the memristor displayed clear synaptic behavior, functioning as an artificial neuron. At high applied bias, the memristor functioned as a binary system memory with non-volatile switching capabilities. The observed properties are thought to result from the coexistence of dual-ion mechanisms in the LiCoO2/boehmite composite layer, with the migration of Li ions and H ions controlling the synaptic effect and non-volatile switching, respectively. This study presents a promising material system for the development of novel multi-functional devices and intelligent electronics.
