Question

Which is not correct about the Schottky defects?

Options

• Both cations and anions are missing from their lattice sites without affecting the stoichiometry of the compound.

• Because of presence of holes the lattice energy decreases.

• The presence of holes causes the density of the crystal to decrease.

• The defect increases the electrical of the ions into the holes.

Answer 1

Because of presence of holes the lattice energy decreases.
