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 ...

The superconducting diode effect allows for nonreciprocal, dissipationless transport. It has the potential to enhance transfer current efficiency compared to the traditional semiconducting equivalent ...

This file type includes high-resolution graphics and schematics when applicable. When devices are being designed to operate at low voltage, it’s often necessary to take into account the voltage drop ...

The invention of blue light-emitting diodes has been awarded the 2014 Nobel Prize in physics. Blue LEDs, when combined with red and green diodes, produce an energy-efficient and environmentally ...

This year's Nobel Prize in physics goes to researchers whose findings you probably rely on just about every day (or, if you're like me, just about every minute). The blue light-emitting diodes they ...

A semiconductor diode is a non-linear device whose most outstanding feature is the fact that, basically, current is only allowed to flow in one direction. The diode is built by joining together two ...

An American physicist and two Japanese colleagues shared the Nobel Prize in physics on Tuesday for creating light-emitting diodes that shine in blue wavelengths — a crucial invention that filled out ...
