← ScienceWhich consequence results when quantum tunneling dominates p-n junction diode reverse bias?
A)Increased reverse current flows✓
B)Depletion region width decreases
C)Minority carrier injection stops
D)Forward voltage drop elevates
💡 Explanation
Increased reverse current flow occurs because electrons tunnel directly through the barrier rather than overcoming it; therefore, reverse breakdown voltage is lower than predicted, rather than normal diode behavior due to doping concentration.
