WitrynaAn impurity defect is a crystal lattice distortion caused by an impurity (foreign atom/ion) occupying an interstitial site in the lattice or replacing the parent atom/ion in the regular sites. Impurity defects can be classified into the following type is: Substitutional impurity. Interstitial impurity. http://mjrahman.buet.ac.bd/Class%20Note3_Jellur.pdf
