Intrinsic & Extrinsic Semiconductors question from NEET 1997 (AIPMT)

Q63NEET 1997 · AIPMTEasy

Intrinsic & Extrinsic Semiconductors

To obtain a p-type germanium semiconductor, it must be doped with

Show answer and solution

Answer: (a)

p-type Ge needs a trivalent acceptor.
Indium is trivalent; P, As and Sb are pentavalent.
So the answer is (a) indium.
