← ScienceWhich consequence results when exceeding silicon bandgap voltage?
A)Avalanche breakdown initiates conduction✓
B)Increased thermal carrier generation
C)Reduced reverse saturation current
D)Decreased depletion region capacitance
💡 Explanation
Avalanche breakdown occurs because high electric fields accelerate carriers, triggering impact ionization; therefore, conductivity increases rather than being limited by thermal generation or depletion capacitance, especially outside normal operating conditions.
