← ScienceWhich consequence results when excessive impurities decrease the band gap in silicon?
A)Increased reverse saturation current✓
B)Increased carrier recombination lifetime
C)Decreased electric field breakdown
D)Decreased gate oxide tunneling
💡 Explanation
Increased reverse saturation current dominates, because band gap narrowing facilitates electron-hole pair generation; therefore, this leakage increases rather than field breakdown or affecting carrier lifetimes because the mechanism is increased thermal carrier liberation across smaller barrier.
