PN Junction Matching Exercise

Identify the thermal equilibrium band diagram to its respective charge distribution. Click on the band diagram and then on its charge distribution. If it is correct, it will turn green; otherwise, it will turn red.

Charge Distribution

None are matching

Region near the junction depleted of mobile carriers
Positive voltage to P-side reduces barrier, allows current flow
Potential difference that develops across the junction in equilibrium
Negative voltage to P-side increases depletion width
