← ScienceWhich conduction change occurs when strain distorts a semiconductor lattice?
A)Change in band gap energy✓
B)Increased electron-phonon scattering
C)Reduced carrier effective masses
D)Enhanced piezoelectric polarization
💡 Explanation
A change in the crystal lattice spacing from strain alters the band structure, causing a change in band gap energy because *lattice deformation potential* modifies electronic energy levels; therefore conduction changes, rather than scattering increasing or carrier densities changing independently from band structure.
