Question

Assertion : The thickness of depletion layer is fixed in all semiconductor devices \ Reason : Free charge carriers are available in depletion layer.

Professor PC Thomas Classes · Answer

(d) : Depletion layer of semiconductor is affected by various factors e.g., 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.
