WebOct 5, 2024 · As a p-type material has an excess number of holes, i.e. fewer electrons, the Fermi level lies closer to the valence band. 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. WebJul 13, 2024 · While in the p-type semiconductor, the acceptor energy level is close to the valence band and away from the conduction band. The impurity added in p-type semiconductor provides extra holes known as Acceptor atoms, whereas in n-type semiconductor impurity provides extra electrons called Donor atoms. mighty robot
