Frenkel defect and schottky defect difference

Why AgBr shows both Schottky as well as Frenkel defect?

WebFrenkel Defect is the defect in the formation of lattice crystals, where an ion or atom occupies a usually vacant site. It is named after the Russian Physicist, Yakov Frenkel. The defect in the crystal is caused by the voluntary spacing out of an atom, which creates a vacancy. The defect is also called dislocation defect which clearly depicts ... WebCorrect options are B) and C) The schottky defect is a vacancy defect (due to missing ions) and also a stoichiometric defect, as the ratio of the number of cations and anions remains the same. (Schottky defects have an effect on the physical properties of solids). It occurs only when there is a small difference in size between cations and anions.
