MCQ
In a junction diode, the holes are due to
- AProtons
- BNeutrons
- CExtra electrons
- ✓Missing of electrons
✓
Answer
Correct option: D.
Missing of electrons
d
(d) In a junction diode, the free electrons combine with a hole and gets converted into a valence electron. Now the thermal energy breaks this electron-hole pair in the depletion layer, the electron drifts to the $n-type$ region leaving behind the hole which drifts to the $p-type$ region.
