Defects are basically irregularities in the arrangement of constituent particles. Broadly speaking the defects are of two types. Namely point defects and line defects. Point defects: The irregularities or deviations from ideal arrangement around a point or an atom in the crystalline substance. Line defects: The irregularities or deviations from ideal arrangement in entire row of lattice points. Answer the following question. Select the correct statements : Frenkel defect create a vacancy defect at its original site and an interstitial defect at its new position. Frenkel defect is also called dislocation defect Silver halide shows Frenkel defect

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 ?
