For six decades, electronic charge transport in oxides has been described by the small‐polaron hopping model. However, this model was developed for binary oxides only. By characterizing structure, site occupation, and transport, in article number 2004490, Maytal Caspary Toroker, Richard D. Robinson, and co‐workers show that the conventional model is inaccurate for oxides with more than two types of cation. They present an accurate model, opening new design avenues for high‐performance devices.
