← ScienceWhich outcome manifests when the Schottky barrier height increases?
A)Rectification weakens, resistance decreases
B)Carrier depletion region thickness grows✓
C)Forward bias current flow increases
D)Minority carrier injection becomes significant
💡 Explanation
Increased Schottky barrier leads to a larger depletion region via Fermi level alignment; because the barrier acts as an energy gap. Therefore, the depletion region grows, rather than the resistance decreasing or current increasing without changes applied to the metal semiconductor junction.
