Galliumarsenide - Wikipedia Galliumarsenide (GaAs) is een anorganische verbinding tussen gallium en arseen.Het is een belangrijke halfgeleider met toepassingen in leds en zonnecellen.Vanwege zijn hoge elektromobiliteit kunnen elektronen erg snel van het ene naar het andere atoom overspringen. Hierom wordt galliumarsenide veel toegepast in geïntegreerde schakelingen waarbij hoge frequenties (tot meer dan 250 GHz ...

Gallium - Wikipedia Gallium is found primarily in the +3 oxidation state. The + oxidation state is also found in some compounds, although it is less common than it is for gallium's heavier congeners indium and thallium. For example, the very stable GaCl2 contains both gallium(I) and gallium(III) and can be formulated as Ga Ga Cl4; in contrast, the monochloride is unstable above 0 &# 76;C, disproportionating into elemental gallium and gallium(III) chloride. Compounds containing Ga–Ga bonds are true gallium(II) compounds, such as GaS
