Crystal defects refer to locations where the internal structural integrity of the crystal is compromised. In the ideal complete crystal, atoms are located in a spatially regular, periodic lattice in a defined sequence. However, in an actual crystal, due to the influence of crystal formation conditions, thermal movement of atoms, and other conditions, the arrangement of atoms cannot be as complete and regular, and there often exist regions that deviate from the ideal crystal structure. These deviations from the complete periodic lattice structure are defects in the crystal that disrupt the symmetry of the crystal.
