From: The role of ion transport phenomena in memristive double barrier devices
Simulation domain of the double barrier memristive device, consisting of an Al2O3 tunnel barrier, a NbxOy solid state electrolyte, and a NbxOy/Au Schottky contact.
Positively charged (red circles) and negatively charged (blue circles) defects are located within the solid state electrolyte. Positively charged defects are assumed to be immobile, negatively charged defects are allowed to move within the solid state electrolyte (i), adsorb at the Au electrode (ii), and desorb from the Au electrode (iii).
