What is an impurity defect? What are
its types? Explain the formation of
vacancies through aliovalent impurity
with example.
Answers
Explanation:
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.two examples of impurity defects???? Solid solutions are example of impurity defects where solute replace the solvent from the crystal sites and occupy those positions. Cation vacancy: when CaCl2 is added to NaCl crystal, one Ca2+ replaces two Na+ ions and generates cation vacancy? A vacancy is produced when an atom is missing from its original lattice site. So vacancy creates an empty lattice site as depicted below. Like other point defects, vacancy is also a zero-dimensional defect.
