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 ...

A single-molecule diode with the highest on–off current (or rectification) ratio to date has been unveiled by a team of physicists and chemists in the US. While single-molecule diodes have been made ...

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 trio of scientists, two from Japan and one from the U.S., will share the Nobel Prize in physics for the invention of blue light-emitting diodes (LEDs), which led to a new, environmentally friendly ...

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 ...

Researchers at the University of Michigan are using high-power diode lasers to study the elementary particle structures of neutrons, electron scattering, and noble gas enhanced magnetic resonance ...

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 ...

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 ...
