Which conduction consequence results from a crystal lattice defect?

A)Increased electron scattering near the defect
B)Uniform enhancement of electric field
C)Decreased phonon scattering overall volume
D)Complete absence of electron mobility

💡 Explanation

Electron scattering increases near a substitutional point defect because the disruption of lattice periodicity affects carrier transport via the mechanism of defect scattering. Therefore, resistivity increases rather than decreases; electron attraction is localized rather than uniform.
