Crystalline imperfections can be classified on the basis of their geometry as follows:
Classification of Crystal Imperfections (or Defects) Crystalline imperfections can be classified on the basis of their geometry as follows: (a) Vacancies (i) Schottky defect (b) Interstitials (i) Frenkel defect (c) Impurities (i) Substitutional impurity (ii) Interstitial impurity (d) Electronic defects (a) Edge dislocation (b) Screw dislocation (a) Grain boundaries (b) Tilt or twist boundaries (c) Twin boundaries (d) Stacking faults (a) Cracks Now we shall discuss the above crystal imperfections, in detail, in the following sections.1. Point Defects
2. Line Defects
3. Surface (or planar) Defects
4. Volume (or bulk) Defects
