An ideal crystal has the same unit cell containing the same lattice points throughout the whole of crystal. But such ideal crystals exist only at 0 K temperature. However, during the formation of crystal structure, certain defects are produced. These defects are point defects, line defects, vacancy defects, interstitial defects or impurity defects. Due to these defect, the crystals exhibit different properties. Presence of delocalised electrons make the metals conductor of electricity . Germanium and silicon are the most important commericial semiconductors. By adding impurities such as arsenic and boron, n and p - type semiconductors can be synthesised. Various combinations of n and p type semiconductors are used to make electronic components. Name the type of point defect that occurs in a crystal of zinc sulphide. Will it increase, decrease or not change the density ?
