Schematic representationof different point defects:
The arrows show the local stresses introduced by the point defects.
Self-interstitials in metals introduce large distortions in thesurrounding lattice ⇒ the energy of self-interstitial
formation is ~ 3 times larger as compared to vacancies (Qi ~ 3×Qv) ⇒ equilibrium concentration of self-interstitials is very low (less than one self-interstitial per cm3 at room T).
