A diode is a semiconductor device that allows electrical current to flow in one direction while blocking it in the other.

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 ...

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 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 ...

Power diodes are a necessary component of all electronics, and are made of a semiconductor material — in most cases silicon — that conduct electrons in one direction. Transphorm’s power diodes are ...
