Which risk increases when applied voltage narrows the quantum well band?

💡 Explanation

Increased Zener tunneling probability appears because band narrowing causes a higher electric field across a smaller effective distance, favouring tunneling. Thus, Zener tunneling increases rather than alternative processes, which depend on different material properties or excitation mechanisms.
