← ScienceWhich 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.
