The diodes are classified into different types based on their working principles and characteristics. These include Generic diode, Schotty diode, Shockley diode, Constant-current diode, Zener diode, Light emitting diode, Photodiode, Tunnel diode, Varactor, Vacuum tube, Laser diode, PIN diode, Peltier diode, Gunn diode, and so on. On a special case, this article discuss about Gunn diode s working, characteristics and applications.

What is a Gunn Diode?

A Gunn Diode is considered as a type of diode even though it does not contain any typic ....etc

P-N junction diode is the most fundamental and the simplest electronics device. When one side of an intrinsic semiconductor is doped with acceptor i.e, one side is made p-type by doping with n-type material, a p-n junction diode is formed. This is a two terminal device.
The effect described in the previous tutorial is achieved without any external voltage being applied to the actual PN junction resulting in the junction being in a state of equilibrium. However, if we were to make electrical connections at the ends of both the N-type and the P- ....etc

viva questions on characteristics of led diode

LED Frequently Asked Questions
LED technology continues to develop rapidly as a general light source. As more LED lighting products are ntroduced on the market, what do retailers, energy efficiency advocates, and consumers need to know to make informed buying decisions?

why the LED emitting light but the PN junction diodes are not?
Injection electroluminescence or the light emitting process in a LED occurs when minority carriers recombine with carriers of the opposite type in a diode's band gap. ....etc

Fabrication of P-N JUNCTION DIODE



BASIC SEMICONDUCTOR
1.1 Semiconductor:-
A semiconductor is a material that has an electrical conductivity between that of a conductor and an insulator. Conductors have very low resistivity (10-2 to 10-8 m) insulator have very high resistivity (>10-2 m), while semiconductors have intermediate values. Semiconductor has resistivity values of order 105 to 100 m.
A semiconductor, such as silicon, has properties somewhere between those of ....etc
