The new diode is made from a single strand of DNA that’s just 11 base pairs long with a small molecule called coralyne inserted at strategic points along its length.

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 ...

Researchers at Ohio State University have discovered a way to make quantum devices using technology common to the chip-making industry today. The team fabricated a device called a tunneling diode ...

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 ...

Gallium oxide (Ga₂O₃) is a semiconductor material that could make electronic devices much more energy-efficient than current ...

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 ...

Silicon carbide (SiC) diodes have already penetrated the quickly expanding solar inverter market, particularly in Europe. Cree's 1200V SiC Schottky ...

Ordinarily, diodes are made from silicon with a p-n (positive-negative) junction at the point of contact between a positively "doped" semiconductor (that is, one that has had its electrical ...
