← ScienceWhich 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.
