Web5 de out. de 2024 · Then for an n-type material that has electrons occupying the conduction band, the energy at which the likelihood of finding an electron is 50% is therefore increased. As at equilibrium, the Fermi levels must match in a p-n -junction, this leads to the p -type conduction band existing at a greater energy relative to the n -type conduction band. WebA PN-junction is formed when an N-type material is fused together with a P-type material creating a semiconductor diode. This tutorial about PN junction theory shows that when silicon is doped with small amounts of Antimony, an N-type semiconductor material is formed, and when the same silicon material is doped with small amounts of Boron, a P ...

WebBased on the type of doping material incorporated, semiconductor crystals are classified into two types particularly n-type semiconductors and p-type semiconductors. Group –V elements such as phosphorus, antimony and arsenic are usually classified as N-type impurities. These elements have five valence electrons.
