Frenkel defect — A Frenkel defect, also called a Frenkel pair or Frenkel disorder, is a compound crystallographic defect in which an interstitial lies near the vacancy. A Frenkel defect forms when an atom or ion leaves its place in the lattice (leaving a vacancy) … Wikipedia
Schottky defect — A Schottky defect is a type of point defect in a crystal lattice named for Walter H. Schottky. The defect forms when oppositely charged ions leave their lattice sites, creating vacancies. These vacancies are formed in stoichiometric units, to… … Wikipedia
Interstitial defect — Interstitials are a variety of crystallographic defects, i.e. atoms which occupy a site in the crystal structure at which there is usually not an atom, or two or more atoms sharing one or more lattice sites such that the number of atoms is larger … Wikipedia
Threshold displacement energy — The threshold displacement energy Td is the minimum kinetic energy that an atom in a solid needs to be permanently displaced from its lattice site to a defect position. It is also known as displacement threshold energy or just displacement energy … Wikipedia
Nitrogen-vacancy center — The nitrogen vacancy center (N V center) is one of numerous point defects in diamond. Its most explored and useful property is photoluminescence, which can be easily detected from an individual N V center. Electron spins at N V centers, localized … Wikipedia
Dislocation — For the syntactic operation, see Dislocation (syntax). For the medical term, see Joint dislocation. In materials science, a dislocation is a crystallographic defect, or irregularity, within a crystal structure. The presence of dislocations… … Wikipedia
