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 ...

As electronic devices become ever more complex, and the densities of components in those devices increases exponentially, we are rapidly approaching the day when the limitations of Moore's Law will be ...

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 ...

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 ...

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 powers) even after ...

[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 ...
