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) gebruikt worden.
