Various types of point defects in crystalline solid
What is meant by imperfections in solid? Classification of defects in crystalline solid is given here. Various types of defects in solid including point defect, line defect, surface defect, and volume defect are briefly discussed here.
Point defect in crystalline solid
What is meant by point defect in crystalline solid? Features and causes of point defect in solid are given here. Various types of point defects such as vacancy, interstitial, self-interstitial, Substitutional, Schottky defect, and Frenkel defect are briefly explained here. Read details…
Vacancy Defect – a type of point defect in crystalline solid
What is vacancy defect in crystalline solids? A vacancy is produced when an atom is missing from its original lattice site. So vacancy creates an empty lattice site as depicted below. Causes of vacancy defects formation, effects and calculation of number of vacancy defects in crystalline solid with example are discussed here. Read details…
Interstitial and Self-Interstitial Defect – a type of point defect
What are interstitial and self-interstitial defects in crystalline solids? Interstitial defect occurs when an atom takes the interstitial position of the lattice structure. This interstitial atom may be of the same crystal or of a foreign material. Causes of interstitial defect formation, effects of interstitial defect are discussed here. Read details…
Substitutional Defect – a type of point defect in crystalline solid
What is substitutional defect in crystalline solid? Substitutional Defect occurs when the original atom in the lattice site of a crystalline solid is replaced by a different type of atom. Causes of substitutional defect formation, effects of substitutional defect are discussed here. Read details…
Schottky Defect – a type of point defect in ionic crystals
What is Schottky defect? It is one type of point defect that occurs in ionic crystals. Schottky defect occurs when oppositely charged atoms (cation and anion) leave their corresponding lattice sites and create a pair of Vacancy Defects. Materials where Schottky defect can be found? Features of Schottky defect and difference with Frenkel defect are also discussed here. Read details…
Frenkel Defect – a type of point defect in ionic crystals
What is Frenkel defect? Frenkel Defect is one type of Point Defect; in fact, it is a combination of both Vacancy and Interstitial type of point defects. Materials where Frenkel defect can be found? Features of Frenkel defect and difference with Schottky defect are also discussed here. Read details…
