Lecoq de Boisbaudran, who named the element gallium after his native land of France (from Latin Gallia meaning Gaul) denied that the element's naming was for a pun on his own name ("le coq" means "the rooster" in French, as does "gallus" in Latin). [13] [14]
Gallium is one of the chief components of blue LEDs. Gallium and its derivatives have only found applications in recent decades. Gallium arsenide has been used in semiconductors, in amplifiers, in solar cells (for example in satellites) and in tunnel diodes for FM transmitter circuits. Gallium alloys are used mostly for dental purposes.
Gallium: 1875 P. E. L. de Boisbaudran: 1878 P. E. L. de Boisbaudran and E. Jungfleisch: Boisbaudran observed on a pyrenea blende sample some emission lines corresponding to the eka-aluminium that was predicted by Mendeleev in 1871. He and Jungfleisch isolated the metal three years later by electrolysis. [136] [137] [52] 70 Ytterbium: 1878 J.C.G ...
Gallium arsenide (GaAs) is a III-V direct band gap semiconductor with a zinc blende crystal structure. Gallium arsenide is used in the manufacture of devices such as microwave frequency integrated circuits , monolithic microwave integrated circuits , infrared light-emitting diodes , laser diodes , solar cells and optical windows.
Gallium is a chemical element with symbol Ga and atomic number 31.. Gallium may also refer to: . Gallium experiment, a neutrino detection experiment also known as GALLEX; Gallium scan or gallium imaging, a method for the detection of infections and cancers
Gallium nitride (Ga N) is a binary III/V direct bandgap semiconductor commonly used in blue light-emitting diodes since the 1990s. The compound is a very hard material that has a Wurtzite crystal structure .
