Applications of PN Junction Diode

What is a PN Junction Diode ?

The PN Junction diode is a semiconductor device that is a combination of n-type and p-type semiconductor materials which are usually made of silicon or germanium. The n-type is always negatively doped and has electrons as its majority charge carriers and the p-type is always positively doped and has holes as its majority charge carriers....

Working of PN Junction Diode

We know that the PN junction is formed by combining the n-type and p-type semiconductor materials. These materials are doped negatively and positively respectively. Due to doping, there are excess electrons and donor ions on the n-side and there are excess holes and acceptor ions on the p-side. The free electrons from the n-side start diffusing towards the p-side and combine with the holes and the acceptor and donor ions are left alone. These ions become immobile and form the depletion layer....
