Ionic Diffusion Properties of Rare-Earth High-Entropy Oxides from a Machine-Learned Interatomic Potential
Oxygen-ion transport in ceria-based rare-earth high-entropy oxides is controlled by vacancy concentration and local Ce–Ce/Ce–Y hopping environments, with diffusion fastest at intermediate vacancy levels and higher Ce content.
