A Frenkel pair is a type of point defect observed in crystalline materials. In this defect, an atom or ion departs from its regular lattice site and occupies an interstitial position within the crystal; the original site left behind becomes a vacancy. As a result, a vacancy and an interstitial atom form a paired entity that balances each other, known as a “Frenkel pair” (Figure 1). The Frenkel defect is a stoichiometric defect, meaning it does not alter the overall composition or electrical neut
