Question

What is the effect of electrical condutivity due to a frenkel defect in a solid?

Answer 1

Compounds having Frenkel defect conduct electricity to a small extent.

When electric field is applied, an ion moves from its lattice site to occupy a hole and thus it creates a new hole.

In this way, a hole moves from one end to another.

Thus, it conducts electricity across the crystal.

Due to presence of holes, stability (or the lattice energy) of crystal decreases.
