Question

To obtain a P-type germanium semiconductor, it must be doped with(a) Arsenic(b) Antimony(c) Indium(d) Phosphorus

Answer 1

option c is correct indium

Answer 2

Answer:

To obtain a P-type germanium semiconductor, it must be doped with(c) Indium.

Explanation:

The addition of trivalent impurities to any intrinsic semiconductor results in the formation of 'holes' or deficiency of valence electrons in the conductor.

The addition of a small amount of impurity to regular crystal structure of germanium produces dramatic changes in its conductivity.
