E) a region where an electron is missing.

Question

Quizplus · Accepted Answer

In a p-type semiconductor, a hole is a region where an electron is missing. This occurs due to the doping of the semiconductor with impurity atoms that have one less valence electron than the host semiconductor atoms, creating a shortage of electrons and thus a deficiency or "hole" in the valence band. These holes can act as positive charge carriers in the semiconductor.
