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 ...

Since their invention in 1962, semiconductor diode lasers have revolutionized communications and made possible information storage and retrieval in CDs, DVDs and Blu-ray devices. These diode lasers ...

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 ...

[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 ...
