Impurity Defects: Causes, Types and Examples

WitrynaPoint Defects: Point defects are where an atom is missing or is in an irregular place in the lattice structure. Point defects include self interstitial atoms, interstitial impurity atoms, substitutional atoms and vacancies. A self interstitial atom is an extra atom that has crowded its way into an interstitial void in the crystal structure. http://mjrahman.buet.ac.bd/Class%20Note3_Jellur.pdf rcv architects
