PN Junction


PN JUNCTION:
Formation:- The N and P-type semiconductors are basic building blocks for semiconductor devices. Joining of N-materials and P- materials type semiconductor forms a PN junction which is importance in electronic systems.
        PN Junction formed by doping of N-type impurity and P-type impurity side by side in a single piece of semiconductor. And it’s called PN Junction diode
