Which effect changes the conduction of a tunnel diode when reverse bias voltage further increases?

A)Reduced tunneling through the barrier
B)Increased electron-hole pair generation
C)Enhanced band-to-band tunneling
D)Elevated minority carrier injection

💡 Explanation

When reverse bias increases, the energy bands align less favorably for tunneling because the depletion region widens, reducing the number of electrons that can tunnel through the barrier. Therefore reduced tunneling results, rather than increased pair generation, enhanced tunneling, or injection, each requiring alternative bias conditions.
