In a junction diode, the holes are due to

Aprotons
Bextra electrons
Cneutrons
Dmissing electrons
Correct Answer

Solution

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.
