gallium arsenide phosphide

It is used standalone or together with gallium arsenide phosphide.

Gallium arsenide phosphide is used for manufacturing red, orange and yellow light-emitting diodes.

A quaternary alloy of Indium gallium arsenide phosphide can be lattice matched for any band gap in between the two.

In 1968, it became the first company to start mass production of (visible) light emitting diodes (LEDs), using gallium arsenide phosphide.

The Monsanto Company was the first organization to mass-produce visible LEDs, using gallium arsenide phosphide in 1968 to produce red LEDs suitable for indicators.

In aperture priority mode, a steadily lit LED indicated the shutter speed automatically set by the electronic microprocessor in response to the light reaching the built-in, open aperture, through-the-lens (TTL), centre-weighted gallium arsenide phosphide photodiode (GPD) light meter and the set lens aperture.
