Solution
The region near the junction of an unbiased junction diode, known as the depletion layer, is depleted of mobile charge carriers (electrons and holes). In the depletion region, the free electrons from the n-type region combine with holes from the p-type region, leaving behind immobile ions.
(2) electrons and holes.
