How is gallium mined
Gallium nitride (GaN) 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. Its wide band gap of 3.4 eV affords it special properties for applications in optoelectronic, high-power and high-frequency devices. For example, GaN is the substrate which makes violet (40… Web1 apr. 2024 · That land in the middle which starts from the northern border with Belarus up to the shores of the Azov Sea, in the south of Donbass.
