WebA 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 … WebJun 14, 2007 · This chapter gives a general overview of the defect types and their origins at the bulk crystal growth.
