← ScienceWhich outcome occurs when the Quasi-Fermi level penetrates a semiconductor's band?
A)Increased conductivity for specific carriers✓
B)Reduced electron-hole recombination rates
C)Decreased Schottky barrier height
D)Enhanced piezoelectric charge generation
💡 Explanation
Increased conductivity happens because *band filling* effect allows more carriers to occupy the bands, therefore increasing the conductance, rather than recombination decrease or barrier adjustments, because Fermi penetration strictly concerns carrier populations.
