A light-emitting diode (LED) is a semiconductor device that emits light when current flows through it. ... or balancing charge carrier injection to increase the EQE ...
A LED is a long-lived light source, but certain mechanisms can cause slow loss of efficiency of the device or sudden failure. The wavelength of the light emitted is a function of the band gap of the semiconductor material used; materials such as gallium arsenide , and others , with various trace doping elements , are used to produce different ...
Carrier generation describes processes by which electrons gain energy and move from the valence band to the conduction band, producing two mobile carriers; while recombination describes processes by which a conduction band electron loses energy and re-occupies the energy state of an electron hole in the valence band.
There are several mechanisms by which minority carriers can recombine, each of which subtract from the carrier lifetime. The main mechanisms that play a role in modern devices are band-to-band recombination and stimulated emission, which are forms of radiative recombination, and Shockley-Read-Hall (SRH), Auger, Langevin, and surface recombination, which are forms of non-radiative recombination.
From this writer's reporting, Gitlin—chief of heating and ventilation giant Carrier Global and a Boeing director since mid-2022—was far and away the frontrunner to lead the embattled ...
From 1 January 1991, the six carriers deployed were divided into Battle Force Yankee (two carriers, including Saratoga, in the Red Sea under Rear Admiral Riley Mixson, Commander, Carrier Group Two/Task Force 155) and Task Force 154, Battle Force Zulu (four carriers in the Arabian Sea/Persian Gulf under Rear Admiral Daniel P. March, Commander ...

The attacks follow the departure of the USS Dwight D. Eisenhower after an eight-month deployment in which the aircraft carrier led the American response to the Houthi assaults.
