Lattice Defects

  • Page ID
  • An ideal crystalline solid exhibit a periodic crystal structure with the positions of atoms or molecules occurring on repeating fixed distances, determined by the unit cell parameters. However, the arrangement of atoms or molecules in most crystalline materials is not perfect and the regular patterns are interrupted by crystallographic defects. Lattice structures (or crystals) are more prone to defects when their temperature is greater than 0 K.
