Which diagram best corresponds to the energy level diagram of a semiconductor?

Question

Quizplus · Accepted Answer

The energy level diagram of a semiconductor typically consists of a valence band and a conduction band separated by a bandgap, with the Fermi level somewhere in between. Choice C is the only diagram that shows this bandgap, with the valence band filled with electrons and the conduction band empty. The other diagrams do not show a clear bandgap or have energy levels that do not correspond to the valence and conduction bands of a semiconductor.
