← ScienceWhich outcome occurs when a semiconductor's depletion region narrows?
A)Increased reverse bias current leakage✓
B)Increased electron-hole recombination rate
C)Increased threshold saturation voltage
D)Increased capacitance within the transistor
💡 Explanation
Increased reverse bias leakage happens because the narrowing depletion region reduces the potential barrier, which lowers resistance to minority carrier flow (drift). This is a result of Zener breakdown, therefore more free electrons flow, rather than enhanced electron-hole recombination that leads to zero current.
