Pn JUNCTION BAND DIAGRAM | Electronics World The energy band diagram of the pn junction under open circuit conditions is shown in Figure 6.11a. There is no net current, so the diffusion current of electrons from the n — to p-side is balanced by the electron drift current from the p — to n-side driven by the built-in field *E0. Similar arguments apply to holes.
