← ScienceWhich 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.
