Frenkel Defect: Definition, Characteristics & Calculation

WebIn Frenkel defect, an ion is displaced from its lattice place to an interstitial place. So, there is no loss or gain of ions in lattice structure. It involves only the migration of the ions within … Even though Frenkel defects involve only the migration of the ions within the crystal, the total volume and thus the density is not necessarily changed: in particular for close-packed systems, the lattice expansion due to the strains induced by the interstitial atom typically dominates over the lattice contraction … See more In crystallography, a Frenkel defect is a type of point defect in crystalline solids, named after its discoverer Yakov Frenkel. The defect forms when an atom or smaller ion (usually cation) leaves its place in the lattice, creating a See more Frenkel defects are exhibited in ionic solids with a large size difference between the anion and cation (with the cation usually smaller due to an increased effective nuclear charge) Some examples of solids which exhibit Frenkel defects: See more • Deep-level transient spectroscopy (DLTS) • Schottky defect • Wigner effect See more • Kittel, Charles (2005).
