Descripción
Sumario:The low- and high-resistance states in Ti/HfO-based memristors were investigated. The statistical analysis of experimental data was carried out with the aid of the fitdistrplus package for the R language and the obtained results were considered in SPICE simulations using the Dynamic Memdiode Model for resistive switching devices. It was found that devices with a large thickness ratio t/t ≥ 0.5 exhibit superior performance in terms of switching stability, variability, and magnitude of the resistance window compared with those with a lower ratio. These observations shed light on the role played by the Ti capping layer in the switching performance of practical memristors, a crucial issue for the potential application of these devices in fields such as information storage and neuromorphic computing.
