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

A)Zener breakdown causes electron tunneling
B)Increased electron mobility, lower resistance
C)Increased band gap to cutoff current
D)Electron flow halts preventing current

💡 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.
