← ScienceWhich outcome increases when silicon's energy band gap narrows?
A)Intrinsic carrier concentration increases rapidly✓
B)Dielectric breakdown strength is enhanced
C)Reverse saturation current decreases markedly
D)Threshold voltage for MOSFET drops
💡 Explanation
An increased intrinsic carrier concentration will increase when an energy band decreases, because a smaller band gap enables smaller excitation energies for electrons via thermal excitation. Therefore, more carriers populate bands, rather than remaining inactive valence electrons given by higher band gap energies.
