Silicon that has been doped with a trivalent impurity is called a (an)
A) n-type semiconductor.
B) p-type semiconductor.
C) pn junction.
D) covalent bond.

Question

Quizplus · Accepted Answer

When silicon is doped with a trivalent impurity, it creates a deficiency of electrons or holes, which act as positive charge carriers. This results in the formation of a p-type semiconductor.
