Answer» Point defects include selfinterstitialatoms,interstitial impurityatoms, substitutional atoms and vacancies. A selfinterstitialatom is an extra atom that has crowded its way into aninterstitialvoid in the crystal structure Impurity defectsare foreign atoms that replace some of the atoms making up the solid or that squeeze into the interstices; they are important in the electrical behaviour of semiconductors, which are materials used in computer chips and other electronic devices. |
