Question

Quizplus · Accepted Answer

P-type semiconductors are created by adding a trivalent impurity (an element with three valence electrons) to a silicon crystal, which has four valence electrons. Gallium (Ga) is a trivalent element, making it the correct choice for creating a p-type semiconductor.
