Which of the following is/are correct about the point defects? 

Options

A. In Frenkel defect, the dielectric constant of solid increases
B. In Schottky defect, the density of solid decreases
C. In Frenkel defect, the density of solid decreases
D. In Schottky defect, the dielectric constant of solid increases

Answer

A, B

Explanation

Due to schottkey defect density of solid decreases because pressnce of holes in crystal. But density reamins unchanged in frenkeldefect. The closeness of similer charges in Frenkel defect tends to increase the dielectric constant of the crystal.
