which element, when doped into silicon, would yield a p-type semiconductor?
This is called an n-type semiconductor. Boron can also be used to dope a pure crystal of silicon. But since boron only offers 3 of. the four electrons that a silicon atom needs, each silicon center is left with a hole. Semiconductors made in this manner are called p-type. In a p-type material if an atom from a neighbouring atom fills the hole, it will leave a. hole adjacent to it.
