Crystallographic point defects

https://en.wikipedia.org/wiki/Crystallographic_defect

Crystalline solids exhibit a periodic crystal structure. The positions of atoms or molecules occur on repeating fixed distances, determined by the unit cell parameters. However, the arrangement of atoms or molecules in most crystalline materials is not perfect. The regular patterns are interrupted by crystallographic defects.

Point defects are defects that occur
only at or around a single lattice point
