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 WebA pn junction is said to be forward biased when the p side of the junction is connected to the positive terminal and n side is connected to the negative terminal of the external … hospitals with mri near me hospitals with nursing shortages
