Which of the following might be used as a dopant in a silicon host to create a p-type semiconductor?

Question

Quizplus · Accepted Answer

Al is commonly used as a dopant in a silicon host to create a p-type semiconductor. It has one less valence electron than silicon, making it a good acceptor dopant. When introduced into the silicon lattice, it creates positively charged holes, which can conduct positive charge in the form of electron deficiencies.
