Abstract
. Our work reveals the existence of a low-energy diffusion pathway involving a concerted "domino effect" of interstitials, with the net result that interstitials can diffuse more readily over longer distances than expected. This observation suggests that defect self-healing can be promoted if the "domino effect" strategy can be engaged.
