di·ode

 (dī′ōd′)
n.
An electrical device, such as a semiconductor or electron tube, through which flow of current is generally restricted to one direction. Diodes are often used in or as rectifiers.

diode

(ˈdaɪəʊd)
n
1. (Electrical Engineering) a semiconductor device containing one p-n junction, used in circuits for converting alternating current to direct current. More formal name: semiconductor diode
2. (Electrical Engineering) the earliest and simplest type of electronic valve having two electrodes, an anode and a cathode, between which a current can flow only in one direction. It was formerly widely used as a rectifier and detector but has now been replaced in most electrical circuits by the more efficient and reliable semiconductor diode
[C20: from di-1 + -ode2]

di•ode

(ˈdaɪ oʊd)

n.
a device, as a two-element electron tube or a semiconductor, through which current can pass freely in only one direction.
[1919; di-1 + -ode2]

diode
The heated cathode generates a cloud of electrons that are attracted by the anode, causing a current to flow from the cathode to the anode. Because the anode cannot generate electrons of its own, the current cannot flow in the opposite direction.

di·ode

(dī′ōd′)
An electron tube or a semiconductor that allows current to flow in one direction only. Diodes can be used to convert AC currents into DC currents.

diode

An electronic device with two electrodes; often used as a rectifier.

This man was very fond of Diocles, a victor in the Olympic games, and when he left his country from a disgust at an improper passion which his mother Alithoe had entertained for him, and settled at Thebes, Philolaus followed him, where they both died, and where they still show their tombs placed in view of each other, but so disposed, that one of them looks towards Corinth, the other does not; the reason they give for this is, that Diodes, from his detestation of his mother's passion, would have his tomb so placed that no one could see Corinth from it; but Philolaus chose that it might be seen from his: and this was the cause of their living at Thebes.
This behavior of an electronic component to allow the current flow in one direction and restrict the flow in opposite direction is known as rectification and hence the name for the diode.
The new diode responds to frequencies up to 50 MHz.
PIN diode attenuators are used extensively in automatic gain control (AGG) and RF leveling applications.
He notes that this advice is based partly on the projected volume increase in diode-pumped unit sales bringing down the cost of replacement diode stacks.
The light-emitting diode is one of the semiconductor diodes, which can turn electrical energy into luminous energy and emit visible light in various colors, such as yellow, green, blue, etc, as well as invisible light, such as infrared and ultraviolet light.
The new diode uses indium phosphide as the semiconductor and replaces the metal with polypyrrole, a polymer that conducts electricity (SN: 8/23/97, p.
In pulsed RF systems, lower control current results in less stored charge in the I-layer reqion of the diode.
Last year, a team of Japanese researchers announced that it had developed gallium nitride (GaN) semiconductor laser diodes that provide a continuous output of blue light at room temperature.
