Science

Which outcome results when the Fermi level shifts within the band structure of a doped semiconductor diode?

A)Minority carrier injection increases dramatically
B)Zener breakdown voltage becomes temperature-independent
C)Majority carrier velocity reaches saturation limit
D)Schottky barrier height proportionally decreases

💡 Explanation

Increased minority carrier injection occurs because the shift alters the population, exponentially increasing minority carriers across the junction, thus raising forward current significantly, rather than Zener variations dependent on doping concentration.
