How it Works? The most common laser diode generates semiconductor or injection laser. In these lasers, a population of Inversion Electrons is produced by applying a voltage across its p-n junction.

In the simple ‘precision rectifier diode’ case, this situation is generally solved using the ‘improved precision rectifier’ (google if need be) circuit, but that would definitely need a negative rail ...

A conventional low-voltage silicon diode has a forward voltage drop of about 0.7V and a relatively low maximum reverse voltage, for example with the 1N4001 rectifier it’s 50V.

Functioning at under several nanometers (a nanometer is a billionth of a meter), the molecular diode studied by the team of researchers acted as a rectifier (diode) because of the chemical ...

US and Russia researchers claim to have produced a reliable molecular diode and have a theoretical model of its operation. “The mechanism for conduction is tunnelling by one electron at a time,” ...

LEDs form an inevitable part in the modern electronics as simple indicators to optical communication devices. Light Emitting Diodes exploit the property of the p-n junction to emit photons when it is ...

Discover the science behind diodes — the tiny components that control the flow of electricity. Learn how they let current pass in one direction, block it in the other, and power everything from ...
