MCQ
The potential barrier, in the depletion layer, is due to
  • Ions
  • B
    Holes
  • C
    Electrons
  • D
    Both $(b)$ and $ (c)$ 

Answer

Correct option: A.
Ions
a
(a) The depletion layer is the region at the junction of a diode which is devoid of ions. Therefore the potential barrier in the depletion layer is due to ions.
