For the first time, researchers in China have demonstrated a high-temperature superconducting diode effect, which allows a ...

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 ...

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 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 ...

A model of a quantum thermal diode based on a qubit and qutrit. The asymmetric design allows this system to behave as a thermal diode when connected between two thermal baths. Credit: APL Quantum ...

Semiconductor diode lasers are everywhere. They created the light pulses that raced along the fibres between our server and yours – allowing you to read this article – and if you stop at the ...

ProLite diode laser delivers 714 W of CW output. Newport's Spectra-Physics division says it has achieved 714 W of continuous wavelength operation using its ProLite diode laser. The result was achieved ...
