Q165 / 180 · KCET 2024 · Physics

Depletion region in an unbiased semiconductor diode is a region consisting of

A
both free electrons and holes
Correct answer
B
neither free electrons nor holes
C
only free electrons
D
only holes

Solution

Depletion region in an unbiased semiconductor diode is a region consisting of immobile ions only. i.e. In depletion region, neither free elements nor holes exist.

Hence, the correct answer is option: 'B'.
