Enhanced Resistive Switching Uniformity in Tantalum Oxide Memristor Devices via Copper Implantation
Advanced Electronic Materials, EarlyView.Metal oxide memristor devices typically suffer from uncontrolled forming processes and limited resistive switching uniformity due to the stochastic formation of an oxygen vacancy filament. Improved resistive switching uniformity in Ta2O5 memristor is developed by Cu implantation in the switching oxide.
