A vacancy defect, also known simply as a vacancy, is a type of point defect that occurs in crystalline solids. It refers to a missed atom in the crystal lattice structure where an atom or ion should be present. Essentially, a vacancy is an empty space where an atom is missing from its regular position in the crystal lattice.
