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 ...

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 ...

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 ...

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 ...

Photonic diode action The first ever “optical” diodes made from the 2D material Ti 3 C 2 and fullerene (or carbon-60) retain their saturable absorption (or increased light transmission at higher laser ...

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

For that he made a matrix of his diodes. The matrix has seven columns, one for each segment on the display. Then there are ten rows, one for each digit from 0 to 9.

A new type of super-thin diode could make flexible displays, solar cells, and light sensors commercially viable.

Until now, diodes had to be made out of two materials with different characteristics. A research team has now discovered a material that makes it possible to create a diode with a simple change in ...
