Moisture effect on the diffusion of Cu ions in Cu/Ta2O5/Pt and Cu/SiO2/Pt resistance switches: a first-principles study

Cu/Ta2O5/Pt and Cu/SiO2/Pt are two of the most promising resistance switches. From experimental observations, it is speculated that the presence of H2O in the amorphous Ta2O5 and SiO2 (a-Ta2O5 and a-SiO2) facilitates the rate-limiting step during the switching process. This rate-limiting step is ess...
