A physicist has made the best ever p-n junction diode from a carbon nanotube. The current-voltage characteristics of the device exhibit an "ideality factor" of one, which is the maximum possible value ...

Diodes allow directed flows of current. Without them, modern electronics would be inconceivable. Until now, they had to be made out of two materials with different characteristics. A research team has ...

A special type of diode made from a crystalline material whose layers are just three atoms thick has been successfully realized for the first time. The superior properties of such ultra-thin crystals ...

An optical diode made with silicon technology can be used for quantum information. Researchers propose using ring resonators to construct a micro-optical diode. The technology is silicon-on-insulator, ...

As electronic devices become ever more complex, and the densities of components in those devices increases exponentially, we are rapidly approaching the day when the limitations of Moore's Law will be ...

[Hales] has been on a mission for a while to make his own diodes and put them to use and now he’s succeeded with diodes made of sodium bicarbonate and water, aluminum tape and soldered copper. By ...

The proof-of-concept uses a van der Waals heterostructure with 2D materials: NbSe 2 – Nb 3 Br 8 – NbSe 2, and is superconducting on one direction, and normally-conducting in the other. Compared with ...
