WebDec 8, 2024 · Because electrons have a negative charge, silicon treated this way is called n-type (negative type). We can also dope silicon with other impurities such as boron, gallium, and aluminum . Silicon treated this way has fewer of those "free" electrons, so the electrons in nearby materials will tend to flow into it. WebSilicon with an n-type impurity added is called n-type silicon. Similarly, silicon with a p-type impurity is called p-type silicon. Because holes predominate in p-type material, they are called “majority carriers.” Electrons are “minority carriers” in p-type materials.
