WebThe PN junctionstructure was shown earlier when introducing band diagram drawing of pn junctions. Let us look at the device structure again shown in figure 1. Figure 1: PN … The p–n junction possesses a useful property for modern semiconductor electronics. A p-doped semiconductor is relatively conductive. The same is true of an n-doped semiconductor, but the junction between them can become depleted of charge carriers, and hence non-conductive, depending on the relative voltages of the two semiconductor regions. By manipulating this non-conductive layer, p–n junctions are commonly used as diodes: circuit elements that allow a flow of
