Which outcome occurs when increased interstitial atoms distort the crystal lattice band?

A)Reduced electron mobility degrades conductivity
B)Increased phonon scattering improves thermal resistance
C)Enhanced spin-orbit coupling increases polarization
D)Augmented electron-hole pairing forms excitons

💡 Explanation

Reduced electron mobility and degraded conductivity will occur because increased interstitial atoms introduce lattice defects, thus causing Bloch wave scattering, deforming the electronic band structure; therefore conductivity decreases, rather than other electronic phenomena occurring.
