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 ...

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 ...

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 ...

Heat management at the nanoscale has long been a cornerstone of advanced technological applications, ranging from high-performance electronics to quantum computing. Addressing this critical challenge, ...

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 ...

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 ...

STOCKHOLM -- Two Japanese scientists and a Japanese-born American won the Nobel Prize in physics on Tuesday for inventing blue light-emitting diodes, a breakthrough that has spurred the development of ...
