WebWhen the forward voltage across the diode equals 0V, forward current (IF) equals 0 mA. When the value starts from the starting point (0) of the graph, if VF is progressively increased in 0.1-V steps, IF begins to rise. When the value of VF is large enough to overcome the barrier potential of the P-N junction, a considerable increase in IF occurs.

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 WebIn forward biasing the external voltage is applied across the PN-junction diode. This voltage cancels the potential barrier and provides the low resistance path to the flow of current. The forward bias means the …
