What is Schottky defect ?

1.	What is Schottky defect ?
Answer» Answer: Schottky defect is basically a vacancy defect shown by ionic SOLIDS. In this defect, an EQUAL number of cations and anions are missing to maintain ELECTRICAL neutrality. It decreases the density of a substance. Significant number of Schottky defects is present in ionic solids. For example, in NaCl, there are approximately 106 Schottky pairs per cm3 at room temperature. Ionic substances containing similar-sized cations and anions show this type of defect. For example: NaCl, KCl, CsCl, AGBR, etc. Explanation:
