I think you you are asking about varactor diode. varactor means variable capacitor. varactor diode is a p-n junction diode which provide a capacitance across it subjected to applied forward and reverse bias.
means it provide variable capacitance which depends on the applied reverse voltage(mostly varactor diode works on reverse voltage).They are also known as varicap
It is a barrier-injection transit-time, a high frequency - semi - structural element of micro-electronics, as the diode is one of the electronic components.
Diode is a Two terminal device which allows flow of curent in forward direction that means it converts DC to AC
I suggest your local electronics parts jobber, or one of the mail order or internet electronics parts stores (e.g. Mouser, DigiKey, Jameco Electronics).
A crystal detector is a diode, often used in non-powered radio receivers. It conducts at a much lower voltage than a typical silicon diode, making it easier to generate the signal amplitude required from the tuning circuit.
in digital electronics, engineers use low voltages like 5 or 12 or 24 volts but when they want to transfer electrical energy in high power which means high voltage and high ampere they use power electronics . in power electronics sometimes the transistor or diode or in power electronics language IGBT and thyristor can work in 10000 volt or higher voltages

a device that conducts in only one direction
Diode
Yes, I am using one in my electronics class currently

It actually means Light Emitting Diode. I hoped i helped :)
Gunn Diodes are used in high frequency electronics. The advantages are increased efficiency and improved temperature stability while a disadvantage is the Gunn Diode can get burned out.
LED stand for Light Emitting Diode.

The alternator diode rectifier converts the AC current being produced by the alternator to DC from which most of the electronics installed and battery use.

In1883 THOMAS EDISON discover the electron and it,s the begning of electronics after that FLEMING discover the diode and then DE FOREST discover the triode which is called transistor
