An international group of physicists has demonstrated that a very thin layer of quantum-mechanical material sandwiched between two pieces of superconductor can conduct electricity with or without ...

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 ...

UNSW researchers have developed an intrinsic-adjusted single-diode model that explicitly accounts for radiative and Auger recombination, improving I–V curve accuracy and reducing root mean square ...

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 ...

Australian semiconductor developer BluGlass has successfully demonstrated working tunnel junction laser diodes in a world-first proof-of-concept using its proprietary remote plasma chemical vapour ...

Although they are a simple device, diodes do have a number of traits to consider. These traits are often application dependent. Some applications include: rectifiers, signal ORing, transistor turn off ...
