Various semiconductor diodes. Left: A four-diode bridge rectifier.Next to it is a 1N4148 signal diode.On the far right is a Zener diode.In most diodes, a white or black painted band identifies the cathode into which electrons will flow when the diode is conducting. Electron flow is the reverse of conventional current flow. [1] [2] [3]A diode is a two-terminal electronic component that conducts ...

Diode Construction. Diodes can be made of either of the two semiconductor materials, silicon and germanium. When the anode voltage is more positive than the cathode voltage, the diode is said to be forward-biased, and it conducts readily with a relatively low-voltage drop.

diode, an electrical component that allows the flow of current in only one direction. In circuit diagrams, a diode is represented by a triangle with a line across one vertex.. The most common type of diode uses a p-n junction.In this type of diode, one material (n) in which electrons are charge carriers abuts a second material (p) in which holes (places depleted of …

The movement of electrons also creates what is known as a depletion layer between the P-type and N-type materials. The depletion layer, also known as a depletion region, is a thin area that's depleted of charge due to the movement, or diffusion, of electrons from the N-type material to the P-type material, and the diffusion of holes from the P-type material to the N-type material.

Dioden sind Halbleiter -Bauelemente. Das heißt, sie bekommen ihre Eigenschaften daher, dass sie auf geschickte Weise dotiert werden. Schematisch besteht sie aus einer p- und n-dotierten Schicht. Diese beiden dotierten Schichten bilden den p-n-Übergang. Es gibt aber auch Dioden, die nicht auf einen solchen Halbleiter-Halbleiter-Übergang basieren.

Resistivity. The electrical Resistance of an electrical or electronic component or device is generally defined as being the ratio of the voltage difference across it to the current flowing through it, basic Ohm´s Law principals. The problem with using resistance as a measurement is that it depends very much on the physical size of the material being measured as well as the material out of ...
