A trivalent impurity has_____
A trivalent impurity has_____
Right Answer is:
3 Valence electrons
SOLUTION
A trivalent atom, the one that has three valence electrons is called an acceptor or recipient. Each acceptor produces one hole in a silicon crystal. In a p-type semiconductor, the holes are the majority carriers, while the free electrons are the minority carriers because of the holes outnumber the free electrons.
