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 atom or molecules in most crystalline materials is not perfect. The regular patterns are interrupted by crystallographic defects.

Famous quotes containing the word defect:
“The child realizes to every man his own earliest remembrance, and so supplies a defect in our education, or enables us to live over the unconscious history with a sympathy so tender as to be almost personal experience.”
—Ralph Waldo Emerson (1803–1882)
