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 ...

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 ...

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 ...

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 at ...

A terahertz device works at room temperature with safe materials. It could make wireless networks faster. Find out how it ...

See this diagram,I've been told the the proprietary drivers offer some extra protection from very short spikes (on power up and shutdown) in the current which laser diodes are very sensitive to and ...
