Band Structure of P-N Junction Semiconductor. The left side, in blue, contains p-type dopant, which provides excess holes, brown circles, as the charge carriers. The right side, in yellow, contains a n-type dopant, which provides excess electrons, green circles, as the charge carriers. The dotted red line represents the Fermi level. We will refer to such a structure as a one- sided abrupt p-n junction. The junction is biased with a voltage Va as shown in Figure. We will call the junction forward-biased if a positive voltage is applied to the p-doped region and reversed-biased if a negative voltage is applied to the p-doped region.
