Diode

A diode can be thought of as the electronic version of a one-way valve. By restricting the direction of movement of charge carriers, it allows an electric current to flow in one direction, but essentially blocks it in the opposite direction.

Diodes may be made from semiconductor materials such as silicon or germanium or may be fabricated using devices depending on thermionic emission: tubes (US) (or valves in UK).
