An extra atom squeezed into a lattice gap

In materials science and solid-state physics, an interstitial is a point defect in which an atom sits in a small gap of the crystal lattice rather than on a normal lattice site, either a foreign atom (as carbon sits in iron) or an extra host atom known as a self-interstitial. Frenkel's 1926 Über die Wärmebewegung in festen und flüssigen Körpern showed that thermal agitation inevitably creates such defects, pairing a displaced atom in an interstice with the vacancy it left behind. The referent is a localized lattice defect that strains the surrounding crystal and speeds diffusion, counted as a defect concentration, and it is a different thing entirely from the fluid between cells, joined to it only by the idea of occupying a gap.[1]
