Here you can read about different types of diodes. A diode can be defined as a device that has two active electrodes. Diodes can be used for various purposes. They conduct electricity in one direction. The most popular type is certainly a semiconductor diode.
Diodes allow electric currents to go to only one direction, and they block the current from the reverse direction. This is known as rectification.
Diodes can be involved in processes that are more complex. Some diodes are used in voltage regulating (that is the case with Zener diodes). You can used them to tune TV or radio receivers, to produce light (these are light emitting diodes), or to make oscillations in radio frequency (this is what tunnel diodes are used for). Tunnel diodes are also used in circuits, since these diodes have negative resistance. You have probably heard of the cat’s whisker diodes. This is the name of semiconductor diodes, invented in 1906. These diodes are consisted of mineral crystals. Modern type diodes are usually made of materials like germanium and silicon. Let us learn more about different types of diodes.

That is why adequate heat-sinking must be provided for the diode to operate properly. The diode is prone to oscillate at low frequencies with the lead inductance from bias circuit connections. A Gunn diode made from gallium nitride can ...
5.9 GUNN DIODE In 1963, Gunn discovered the transferred electron effect which is now commonly referred to a Gunn effect. This effect is effectively utilised in the Gunn diode for generation of microwave oscillations.
However, IMPATT diodes with doping variations are known as excellent microwave generators. 8.4 Gunn Diode It is n-type GaAs diode working with different conduction band energy levels. Transferred electron mechanism indicates for ...
