In the fascinating realm of materials science, Schottky defects are crucial imperfections that significantly influence the electrical properties of solid materials. Named after the German physicist Walter H. Schottky, these point defects occur when pairs of oppositely charged ions are missing from their lattice sites within a crystal structure. Schottky defects play a vital role in material conductivity and have profound implications for various applications. In this article, we will explore the intriguing world of Schottky defects in solids, examining their formation, effects on material properties, and their relevance in different fields.
