Quick Summary

Gallium arsenide phosphide (GaAsP) is a synthetic compound used as a semiconducting material. It is formed by combining gallium, arsenic, and phosphorus. Gallium itself is a soft, silvery-white metal that liquefies just above room temperature, with a melting point of approximately 29.76 °C (85.57 °F).12

Gallium arsenide (GaAs) is a specific compound of gallium and arsenic, also known for its semiconducting properties and use in electronic devices. Compounds like GaAsP, gallium arsenide (GaAs), and gallium nitride (GaN) are valuable for their semiconductor and optoelectronic characteristics, finding applications in devices such as transistors, rectifiers, light-emitting diodes (LEDs), and semiconductor lasers.12

Nick Holonyak, Jr.
By using the semiconductor material gallium arsenide phosphide (GaAsP) and the technique of stimulated emission, in 1962 Holonyak succeeded in operating the first practical visible LED device. Holonyak’s device emitted red light. After LEDs that produce green and blue light were developed (in the 1970s and ’90s, respectively), LEDs that…
