1. p-n junction behaves as a capacitor when forward biased.
2. p-n junction has p and n type semiconductors with depletion layer in between.
3. p-n junction has a wider depletion layer as compared to a Zener diode.
Consider the following statements about semiconductors?
1. The forbidden energy gap in semiconductors lies between the valence band and conduction band.
2. The forbidden energy gap in germanium at 0 K is about 0.72 eV.
