← TechnologyWhich outcome occurs when accumulated charge neutralizes at a p-n junction?
A)Increased reverse saturation current
B)Depletion region width shrinks✓
C)Minority carrier injection increases
D)Built-in potential becomes amplified
💡 Explanation
Neutralization reduces the potential barrier at the junction. This prompts depletion region collapse because the depletion region width is directly influenced by junction potential; therefore, shrinking occurs rather than increased current or potential amplification as charge is reduced.
