Web28 de mai. de 2015 · An n-type semiconductor has an excess of 'free' electrons -- electrons that can move about freely in the semiconductor (very similar to electrons in a metal). These electrons are 'donated' by immobile donor impurities doped in to the semiconductor. If you imagine starting from that state, then the result is still neutral. WebThese charge carriers are produced by thermal excitation. In intrinsic semiconductors, the number of excited electrons and the number of holes are equal: n = p. Electrons and holes are created by the excitation of an electron from the valence band to the conduction band. An electron-hole (often simply called a hole) is the lack of an electron ...

WebAn N-type semiconductor is doped with a pentavalent impurity to create free electrons. Such material is conductive. The electron is the majority carrier. P-type semiconductor, doped with a trivalent impurity, has an abundance of free holes. These are positive charge carriers. The P-type material is conductive. The hole is the majority carrier.
