Essentially, every electronic device in use today involves semiconductors, which can either inhibit or enhance the flow of electrons in one direction, allowing precise control over electrical signals.

An electronic diode is a nonlinear semiconductor circuit component that allows conduction of electrical current in one direction only. A component with similar functionality for electromagnetic waves, ...

A diode is a device that allows electric current to flow in only one direction, from its anode towards its cathode but not the other way around. There is plenty of online material explaining diode ...

A diode allows current to travel in only one direction. With that in mind, [Alex] built a mechanical diode that will only allow gear rotation in one direction to be transmitted through the system. … ...

A semiconductor diode is a key component in rectifier circuits, allowing the flow of electric charge in only one direction. A semiconductor rectifier diode is a two-terminal electronic device that ...

A superconducting diode effect was observed in an Fe(Se,Te)/FeTe heterostructure, enabling current to preferentially flow in one direction under varying temperatures and magnetic fields.
