← ScienceWhich outcome occurs when a semiconductor diode's reverse bias widens which region of its band structure?
A)Depletion region widening and reduced capacitance✓
B)Increased forward current, minimal reverse breakdown
C)Increased electron 'doping' around active region
D)Reduced energy band slope; increased conduction
💡 Explanation
Widening reverse bias causes depletion width increase via *increased band bending*, therefore reducing junction capacitance, because a larger depletion region has fewer mobile charge carriers rather than increased ones or conduction changes.
