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.
Doping Silicon. You can change the behavior of silicon and turn it into a conductor by doping it. In doping, you mix a small amount of an impurity into the silicon crystal. There are two types of impurities: 1  N-type-In N-type doping, phosphorus or arsenic is added to the silicon in small quantities.2  Phosphorus and arsenic each have five outer electrons, so they're out of place when they get into the silicon lattice.3  The fifth electron has nothing to bond to, so it's free to move around.here are two types of impurities: 1  N-type-In N-type doping, phosphorus or arsenic is added to the silicon in small quantities. 2  Phosphorus and arsenic each have five outer electrons, so they're out of place when they get into the silicon lattice.
