When trivalent elements are used in doping, the resulting material is called material and has an excess of .
A) n-type; valence-band holes
B) n-type; conduction-band electrons
C) p-type; valence-band holes
D) p-type; conduction-band electrons

Question

Quizplus · Accepted Answer

Trivalent elements used in doping create p-type semiconductor materials, which have an excess of valence-band holes due to the missing electron in the trivalent dopant's outer shell, leading to the creation of holes in the valence band.
