← ScienceWhich outcome occurs when depletion region width decreases?
A)Increased electron tunneling probability✓
B)Suppressed reverse saturation current
C)Reduced avalanche breakdown voltage
D)Enhanced Schottky barrier formation
💡 Explanation
Electron tunneling probability increases exponentially with decreasing width because the quantum mechanical wave function has a greater overlap on the other side of the barrier. Therefore increased tunneling. rather than other effects driven by drift under electric field.
