Which outcome results when impurity atoms distort a crystal lattice?

A)Mobility of charge carriers decreases
B)Thermal conductivity is largely unaffected
C)Elastic modulus shows great enhancement
D)Dielectric breakdown strength increases

💡 Explanation

The distorted lattice changes the periodicity experienced by electrons; therefore, electron scattering increases with increasing impurity concentration because of a reduction in the mean free path and mobility rather than other options.
