crystallographic defect

crystallographic defect (plural crystallographic defects)

1. (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
