A semiconductor for which it is true that the major charge carriers are electrons
A)is called an n-type semiconductor.
B)is called a p-type semiconductor.
C)accepts positive charges from filled valence bands.
D)is devoid of acceptor levels.
E)None of these is correct.

Question

Quizplus · Accepted Answer

An n-type semiconductor is doped with impurities that have extra electrons, also known as donor impurities. These extra electrons become the major charge carriers, hence making it true that the major charge carriers are electrons. A p-type semiconductor, on the other hand, is doped with impurities that have fewer electrons, known as acceptor impurities, which create holes as the major charge carriers. Option C and D are incorrect since they do not provide an accurate explanation. Option E is incorrect since option A is correct.
