Which conduction outcome results because defects modulate band gaps?

A)Increased n-type semiconductor conductivity
B)Decreased electron-hole recombination rate
C)Increased intrinsic semiconductor resistance
D)Decreased phonon scattering effects

💡 Explanation

Increased n-type conductivity occurs through donor level creation from defects; this is the mechanism. Impurities introduce energy levels within the band gap, therefore, more electrons are available for conduction, rather than decreased resistance. Conductivity increases.
