Nick Holonyak Jr., pioneer of LED lighting, awarded Queen

Working at General Electric on Oct. 9, 1962, Holonyak demonstrated the first visible-light-emitting diode. While infrared LEDs previously had been made of the material gallium arsenide, Holonyak created crystals of gallium arsenide phosphide – the first time the three elements had crystalized together – to make an LED that would emit a visible red light.

List of semiconductor materials - Wikipedia

A compound semiconductor is a semiconductor compound composed of chemical elements of at least two different species. These semiconductors typically form in periodic table groups 13–15 (old groups III–V), for example of elements from the Boron group (old group III, boron, aluminium, gallium, indium) and from group 15 (old group V, nitrogen, phosphorus, arsenic, antimony, bismuth).
