crystallographic defect

== English == === Noun === crystallographic defect (plural crystallographic defects) (crystallography) A localized disruption in the perfect, repeating arrangement of atoms in a crystal lattice, occurring at a single point or around one atom, significantly influencing material properties like conductivity and strength; the main types include vacancies (missing atoms), interstitials (extra atoms in non-regular spots), and substitutional defects (impurities replacing host atoms). Hyponyms: point defect, line defect, planar defect, bulk defect Coordinate terms: volume defect, F-center ==== Hyponyms ==== point defects: anion vacancy F-center Frenkel defect Schottky defect line defect planar defect bulk defect (or volume defect)
