← ScienceWhich mechanism dictates semiconductor conductivity due to thermal excitation?
A)Band gap energy overcoming depletion width
B)Increased intrinsic carrier concentration overcomes doping✓
C)Auger recombination reduces free carrier lifetime
D)Phonon scattering limits carrier mean free path
💡 Explanation
Thermal excitation increases conductivity because band to band excitation generates more electron-hole pairs; this intrinsic carrier concentration is the dominant effect, therefore conductivity increases proportionally, rather than being limited by phonon scattering alone.
