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 ...

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.

Researchers have discovered the mechanism for supercurrent rectification, in which current flows primarily in one direction in a superconductor. By using a specific iron-based superconductor, they ...

Diodes allow directed flows of current. ... 2025 — Researchers have discovered the mechanism for supercurrent rectification, in which current flows primarily in one direction in a superconductor.

Electrical diodes, which allow currents to flow in one direction but not the other, are a fundamental component of electronics. Engineers have long sought a comparable device that would direct ...
