Valence change detection in memristive oxide based heterostructure cells by hard X-ray photoelectron emission spectroscopy
The switching mechanism of valence change resistive memory devices is widely accepted to be an ionic movement of oxygen vacancies resulting in a valence change of the metal cations. However, direct experimental proofs of valence changes in memristive devices are scarce. In this work, we have employe...
