We find two distinct self-interstitial forms - a simple one with low entropy and a complex one with entropy ~30 k at the migration saddle point. The latter dominates diffusion at high temperature. We propose that its structure is similar to that of an amorphous pocket - we name it a 'morph'. Computational modelling suggests that morphs exist in both self-interstitial and vacancy-like forms, and are crucial for diffusion and defect dynamics in Ge, Si and probably many other crystalline solids","authors_text":"Ardechir Pakfar, Chihak Ahn, Davide De Salvador, Elena Bruno, Enrico Napolitani, Jean-Michel Hartmann, J\\'er\\^ome Valentin, Jonathan P.
