PN JUNCTION DIODE AND ITS. CHARACTERISTICS. In chapter 1 – Understanding the PN junction , we have seen how a PN junction is formed from a p-type and n-type semiconductor. We have also learned about diffusion current, depletion region, drift current and barrier potential. If you find these terms foreign, just read
The p-n junction is a versatile element, which can be used as a rectifier, as an isolation structure and as a voltage-dependent capacitor. In addition, they can be used as solar cells, photodiodes, light emitting diodes and even laser diodes. They are also an essential part of Metal-Oxide-Silicon Field-Effects-. Transistors
P-N Junction Diode. (a) Construction. It is a two-terminal device consisting of a P-N junction formed either in Ge or Si crystal. Its circuit symbol is shown in Fig. 52.1 (a). The P-and N-type regions are referred to as anode and cathode respectively. In Fig. 52.1 (b), arrow- head indicates the conventional direction of current flow.
Before going to the discussion of diode, we have to check the details of P-N junction. P-N junction can be defined as the junction formed at combining point of P-Type & N-type material. The interface between the two regions is called as metallurgical junction. At this junction we can also observe that depletion region will be

The p-n junction is the fundamental building block of the electronic age. available bonding electrons gives phosphorus its distinct chemical properties. For p-n junctions the important aspect is that phosphorus has one more electron available for bonding than battery is connected to a diode, current will flow only when.
