E) a region where an electron is missing.

Question

Quizplus · Accepted Answer

In a p-type semiconductor, the doping material introduces impurities with fewer valence electrons (such as boron) than the host material (such as silicon). This creates a deficiency of electrons or "holes" in the crystalline structure, which can be thought of as an area where an electron is missing. Therefore, the best choice is E.
