← ScienceWhich effect results from imperfections influencing electron mobility within semiconductors crystal lattices?
A)Increased electrical resistance overall✓
B)Enhanced light absorption spectrum
C)Improved thermal conductivity metrics
D)Reduced refractive index ratings
💡 Explanation
Increased resistance occurs because lattice defects scatter electrons, diminishing the mean free path via phonon scattering; therefore, resistance rises, rather than better conductivity. Impurities impact electron flow, not primarily the absorption/refraction/transmission behaviour.
