How does the addition of trivalent impurity to a pure semiconductor affect the electron hole pairs at room temperature?

Expert Answer:

At room temperature, electron hole pairs are created in a pure semiconductor; there being as many holes as the number of electrons. However, with the addition of trivalent impurity, the holes far outnumber the electrons.
