Which of the following could act as a p-type semiconductor?

Question

Quizplus · Accepted Answer

Silicon with traces of boron can act as a p-type semiconductor because boron has one less valence electron than silicon, making it a group III element. When boron is substituted for silicon in the crystal lattice, it creates a "hole" where a valence electron would normally be, creating a net positive charge and allowing for the semiconductor to conduct positive charge (i.e., holes).
