Verified Solution4 OptionsUpdated: October 2026👁️1 View
Share:
- 1The depletion layer remains unchanged, but the minority carrier concentration increases exponentially.
- 2The junction enters a state of breakdown where current increases regardless of the barrier voltage.
- 3The applied potential opposes the internal barrier voltage, narrowing the depletion layer and allowing majority carriers to cross the junction.✓
- 4The applied potential increases the width of the depletion layer, preventing current flow.
Correct answer
The applied potential opposes the internal barrier voltage, narrowing the depletion layer and allowing majority carriers to cross the junction.
