Mechanism of resistive switching in HfOx-based memristors

We conducted an in-depth study of the resistance-switching mechanism in classical HfOx-based devices. Through atomic-level characterisation of the dynamic evolution of conductive filaments, we confirmed that the filament system in this type of device has a quasi-core-shell structure, consisting of a metallic Hf6O core and an insulating HfO2 crystalline shell. constitute. The study pinpointed multiple […]

A universal Monte Carlo model for RRAM switching

A universal Monte Carlo simulator is developed based on a cell switching model and a tunneling-based transport model. Driven by external electric field, the growing process is …

An overview of RRAM

This review discusses recent advances to improve the switching performance via the conductive filament modulation, including material modulation, device structure design, and switching operation scheme optimization …
