Although photoluminescence from gallium-arsenide (GaAs) deep-centers was first observed in the 1960s, semiconductor lasers have always utilized conduction-to-valence-band transitions. Here we review recent materials studies leading to the first GaAs deep-center laser. First, we summarize well-known properties: nature of deep-center complexes, Franck-Condon effect, hotoluminescence.
Aluminium gallium arsenide epi wafer . Aluminium gallium arsenide epi wafer (AlGaAs or AlxGa1−xAs) is a semiconductor wafer material with very nearly the same lattice constant as GaAs, but a larger bandgap. The x in the formula above is a number between 0 and 1 – this indicates an arbitrary alloy between GaAs and AlAs.
Gallium is not produced in the United States, and demand is satisfied by imports, primarily high-purity material from France and low-purity material from Kazakhstan and Russia. More than 95% of gallium consumed in the United States is in the form of gallium arsenide (GaAs). Analog integrated circuits are the largest application for gallium, with optoelectronic devices

Gallium Nitride is a binary III/V direct bandgap semiconductor that is well-suited for high-power transistors capable of operating at high temperatures. Since the 1990s, it has been used commonly in light emitting diodes (LED). Gallium nitride gives off a blue light used for disc-reading in Blu-ray.
Sep 20, 2011· The center of the gallium split-interstitial pair is 0.85 Å below the ideal gallium lattice site, as shown in Fig. 5(b). The distance between the two gallium atoms of this split interstitial is 2.74 Å, which is 15% farther than the calculated bulk gallium arsenide nearest neighbor distance of 2.40 Å.

Aug 23, 2019· What is Gallium Arsenide? Gallium arsenide (GaAs) is a compound built from the elements gallium and arsenic. It is often referred to as a III-V compound because gallium and arsenic are in the III group and V group of the periodic table, respectively. Figure 1. The gallium arsenide compound. Brown represents gallium and purple represents arsenic.
