WebIn the Schottky defect, two ions of opposite sign leave the lattice. Impurity defects are foreign atoms that replace some of the atoms making up the solid or that squeeze into the interstices; they are important in the electrical behaviour of semiconductors, which are materials used in computer chips and other electronic devices. WebSchottky defect is a type of point defect in which vacancies of ions occur at some points in the crystal lattice. This defect is stoichiometric in nature i.e., the stoichiometry of the crystal does not change with this defect as the number of cations and anions that are missing are equal in number.
