Indium gallium arsenide (InGaAs) and gallium-indium arsenide (GaInAs) are used interchangeably. According to IUPAC standards the preferred nomenclature for the alloy is GaxIn1-xAs where the group-III elements appear in order of increasing atomic number, as in the related alloy system AlxGa1-xAs. By far, the most … Visa mer Indium gallium arsenide (InGaAs) (alternatively gallium indium arsenide, GaInAs) is a ternary alloy (chemical compound) of indium arsenide (InAs) and gallium arsenide (GaAs). Indium and gallium are ( Visa mer GaInAs is not a naturally-occurring material. Single crystal material is required for electronic and photonic device applications. … Visa mer Single crystal GaInAs Single crystal epitaxial films of GaInAs can be deposited on a single crystal substrate of III-V … Visa mer The synthesis of GaInAs, like that of GaAs, most often involves the use of arsine (AsH 3), an extremely toxic gas. Synthesis of InP likewise most often involves phosphine (PH 3). Inhalation of these gases neutralizes oxygen absorption by the bloodstream … Visa mer InGaAs has a lattice parameter that increases linearly with the concentration of InAs in the alloy. The liquid-solid phase diagram shows that during solidification from a solution … Visa mer Photodetectors The principal application of GaInAs is as an infrared detector. The spectral response of a GaInAs photodiode is shown in Figure 5. GaInAs photodiodes are the preferred choice in the wavelength range of 1.1 μm < λ < 1.7 μm.
