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. WebMay 22, 2024 · A semiconductor with an excess of holes is called p-type. Silicon typically has four valence electrons which are involved in bonding. Phosphorous has five valence electrons, and aluminum has three. ... For this reason in a p-type material, \(E_f\) is closer to the valence band than the middle of the energy gap. An n-type material has an excess ...

WebA p-type or an n-type semiconductor is not very useful on its own.However, joining these opposite materials creates what is called a p-n junction. A p-n junction forms a barrier to conduction between the materials. Although the electrons in the n-type material are attracted to the holes in the p-type material, the electrons are not normally energetic … WebThe n-material has lost electrons, and p material has acquired electrons. The n material is thus positive relative to the p material. Since this potential tends to prevent the movement of electron from the n region into the p region, it is often called a barrier potential.
