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 ... WebAn extrinsic semiconductor doped with electron donor atoms is called an n-type semiconductor because most charge carriers in the crystal are negative electrons. Since silicon is a tetravalent element, the normal crystal structure contains 4 covalent bonds from four valence electrons. pool shoppeWebAn electric field E forms between the positive ion cores in the n -type material and negative ion cores in the p -type material. This region is called the "depletion region" since the electric field quickly sweeps free carriers out, hence the region is depleted of free carriers.
