Which consequence will occur when electrons tunnel through depletion regions?

A)Increased reverse bias current flow
B)Decreased Zener diode breakdown
C)Enhanced electron-hole recombination events
D)Suppressed avalanche shot noise production

💡 Explanation

Increased reverse current results because quantum mechanical tunneling allows electrons to traverse the high-field depletion region, despite the barrier, especially in heavily doped semiconductors, rather than impact ionization dominating.
