inst.eecs.berkeley.eduIn a diode formed from a direct band-gap semiconductor, such as gallium arsenide, carriers that cross the junction emit photons when they recombine with the majority carrier on the other side. Depending on the material, wavelengths (or colors) from the infrared to the near ultraviolet may be produced. The forward

www.analog.commicrowave integrated circuit (MMIC) amplifier using gallium arsenide (GaAs), pseudomorphic high electron mobility transistor (pHEMT) technology. This 2 mm × 2 mm LFCSP amplifier can be used as either a cascadable 50 Ω gain stage, or to drive the local oscillator (LO) port of many of the single and double balanced mixers from Analog
Gallium - USGS
pubs.usgs.govGlobally, primary gallium is recovered as a byproduct of processing bauxite and zinc ores. One company in Utah recovered and refined high-purity gallium from imported primary low-purity gallium metal and new scrap. Imports of gallium metal and gallium arsenide (GaAs) wafers were valued at about $1 million and $150 million, respectively.
