Professor`s notes on pn junctions
... As indicated by section 8.2 the electrical properties are a consequence of the thermal equilibrium process in which a localized migration of electrons, from the n–side to the p–side, takes place in order to reach energy balance. Naturally, such a migration of electrons also represents a transfer of ...

There is no electric field within a conductor in statics because otherwise an electron would experience a force and would move.) Electron Volt (eV)A unit used to deal with the e ...
