AIIMS 2019 Physics Doping MCQ Question

Doping an intrinsic semiconductor with impurities introduces additional charge carriers, either electrons (n-type doping) or holes (p-type doping), which significantly enhances its conductivity. This increase occurs because the dopants provide extra charge carriers that facilitate electrical conduction, thus increasing the overall conductivity of the material. Options B, C, and D are incorrect because doping does not decrease conductivity (B), maintain it (C), or eliminate it (D); rather, it actively improves the semiconductor's ability to conduct electricity.
