Question

Assertion : The thickness of depletion layer is fixed in all semiconductor devices.
Reason: Free charge carriers are available in depletion layer.
A. If both assertion and reason are true and reason is the correct explanation of assertion.
B. If both assertion and reason are true not but reason is not the correct explanation of assertion.
C. If assertion is true but reason is false
D. If both assertion and reason are false.

Answer 1

Correct Answer - D
Depletion layer of semiconductor is affected by various factors eg. biasing, temperature etc. So thickness of depletion layer is not fixed in all semiconductor devices. In depletion layer, negatively and positively charged immobile ions are present. Therefore no free charge carriers are available in depletion layer
