Researchers have created a diode out of a 1 nm-sized single molecule with high rectification ratios. Diodes, commonly used in in everyday electronic devices, allow current to flow in one direction ...

A semiconductor diode is an electronic component that allows current to flow in only one direction, acting like a one-way valve for electricity. It is commonly used for voltage regulation ...

Duke University engineers have developed a new way of producing thermal diodes, devices which regulate heat to preferentially flow in a certain direction, effectively creating a thermal conductor ...

The electronic diode is a device that allows current to travel in one direction but not the other. That makes them handy things to have around. So handy, in fact, that you’d be hard pressed to ...

Photonics researchers have achieved the extra-ordinary by creating a diode consisting of light that can be used, for the first time, in miniaturised photonic circuits.

This is converted to DC by a network of diodes that only allow current to flow in one direction. Diodes, however, have to switch on and off, which takes time. This is where the problem lies.

And when they looked, they found that they’d made a one-way superconductor. What Ali’s group has created is very much like a diode: a component that only conducts electricity in one direction.
