Semiconductors are a high-yield, conceptual, and scoring topic in NEET Physics (NCERT Class 12, Chapter 14), frequently yielding 2–3 direct questions on PN junctions, logic gates, and transistors. Mastering this topic, including intrinsic/extrinsic types, doping, and band theory, ensures easy marks while providing foundational knowledge for electronic diagnostic tools used in medicine.
