As mentioned earlier, a Schottky defect will always result a crystal structure in equilibrium--where no crystal is going to be … WebConsequences of Schottky Defect As the number of ions decreases as a result of this defect, the mass decreases whereas the volume remains the same. Hence density of the solid decreases The crystal begins to …
WebTwo atoms reduce from the crystal for each Schottky defect. The number of atoms present in the crystal before and after Frenkel defect remains same. Due to vacancy formation, Schottky defect reduces density of the solid. Density of the solid crystal before and after Frenkel defect remains same as no atom leaves the solid. Common materials where ...
WebApr 21, 2024 · The defect produced due to vacancies caused by the absence of anions and cations in the crystal lattice is called the Schottky defect.
