Which mechanism causes suppressed conductivity when dislocations distort a crystal?

A)Reduced electron mean free path
B)Increased interatomic forces
C)Enhanced phonon scattering rate
D)Modified nuclear spin arrangements

💡 Explanation

Deformations in crystal lattices shorten electronic wavelengths through lattice distortions, because this introduces defects that disrupt periodic electron flow, reducing the mean free path; thus, electrical conductivity decreases, rather than increasing resistance from phonon scattering under thermal effects.
