Which one of the following is an n-type of semiconductor?
A)alumina
B)germanium doped with antimony
C)germanium doped with boron
D)tellurium

Question

Quizplus · Accepted Answer

N-type semiconductors are produced by doping a pure semiconductor (such as germanium) with atoms that have one more valence electron, such as antimony or phosphorus. This creates an excess of free electrons, which are the charge carriers in the semiconductor. Therefore, Germanium doped with Antimony (choice B) is an n-type semiconductor.
