Web1. Frenkel-type defect ((Problem)) N atoms are arranged regularly so as to form a perfect crystal. If one replaces n atoms among N atoms (1 n N) from the lattice sites to interstices of the lattice, this becomes an imperfect crystal with n defects of the Frenkel type. The number N’ of the interstitial sites into which an atom can enter is of the same order of …
