Schottky defect is usually favoured by a very small difference in the sizes of cation and anion.

Metal excess defect due to absence of anion in NaCl crystal leads to paramagnetism in NaCl crystal

Non -stoichiometric defect in ${\mathrm{Cu}}_2\mathrm{O}$ develops $n$-type semi conduction

Vacancy defect decreases density of crystal.
