Introduction to Elasticity Theory for Crystal Defects

WebThe defects distribute in a swirl pattern reflecting melt convection, rotation of the crystal, and temperature fluctuations at the solid–melt interface during crystal growth. A thermal oxidation process followed by an oxide strip and preferential etchant is generally required to observe these defects ( Huff 1992 ).

WebSelf-sufficient and user-friendly, this book provides a complete introduction to the anisotropic elasticity theory necessary to model a wide range of crystal defects. Assuming little prior knowledge of the subject, the reader is first walked through the required basic mathematical techniques and methods. WebThere are basic classes of crystal defects: point defects, which are places where an atom is missing or irregularly placed in the lattice structure. Point defects include lattice vacancies, self-interstitial atoms, substitution impurity atoms, and interstitial impurity atoms. linear defects, which are groups of atoms in irregular positions.
