Which outcome occurs when significant external electric field is applied to semiconductor?

💡 Explanation

Zener breakdown happens because strong electric fields cause electron tunneling through the material's forbidden gap. Therefore, electron tunneling increases current rather than blocking. This applies until the junction is destroyed; the effect rather than simple conductivity increase.
