ELECTRONIC DEVICES – p-n junction diode
1. SEMI CONDUCTOR The electrons in the valence band are bound to the atoms of the crystal. They need to have enough extra energy to go across the forbidden band gap to get into the energy levels of the conduction band. To quantify electron concentration, count the number of electrons in the conduction band per a unit volume, typically a cm3. This is shown by the symbol n. When the system is in…
