For a pure semiconductor the Fermi level is:
A)in the conduction band
B)well above the conduction band
C)in the valence band
D)well below the valence band
E)near the center of the gap between the valence and conduction bands

Question

Quizplus · Accepted Answer

In a pure semiconductor, the Fermi level lies near the center of the gap between the valence and conduction bands. This is because pure semiconductors have no impurities or dopants that introduce energy levels within the band gap, and so the Fermi level must lie in the middle to maintain charge neutrality.
