Which of the following statements is not correct when a junction diode is in forward bias?

Which of the following statements is not correct when a junction diode is in forward bias?
  1. The width of depletion region decreases.
  2. Free electrons on $n$-side will move towards the junction.
  3. Holes on p-side move towards the junction.
  4. Electron on $n$-side and holes on $p$-side will move away from junction.

Solution

In forward biasing both electrons and protons move towards the junction and hence the width of depletion region decreases.
