A Schottky defect is an excitation of the site occupations in a crystal lattice leading to point defects named after Walter H. Schottky. In ionic crystals, this defect forms when oppositely charged ions leave their lattice sites and become incorporated for instance at the surface, creating oppositely charged vacancies. These vacancies are formed in stoichiometric units, to maintain an overall neutral charge in the ionic solid. WebAug 21, 2024 · The flickering clusters increase as temperature drops below 277 K, and the water density decreases as a result. The missing and lacking of atoms or ions in an ideal or imaginary crystal structure or lattice and the misalignment of unit cells in real crystals are called crystal defects or solid defects.

WebThis question can be answered in two ways, as follows: (1) Yes, Schottky defects can exist in K2O; each defect will consist of one O2- vacancy and two K+ vacancies. (2) No, in the strict sense, Schottky cannot exist in K2O if we consider this type of defect to consist of a cation-anion pair; for every O2- vacancy created there must exist two K+ vacancies.
