← ScienceWhich outcome occurs when the energy levels broaden considerably in doped semiconductor bands?
A)Increased free carrier concentration results✓
B)Reduced electron-phonon scattering appears
C)Increased exciton binding happens
D)Reduced electrostatic repulsion arises
💡 Explanation
Increased overlap in doped bands leads to enhanced free carrier concentration because dopants introduce extra electrons/holes. Therefore, conductivity rises rather than being impeded by scattering/repulsion because broadened bands facilitate electron mobility.
