PAM XIAMEN offers InAs Indium Arsenide Single Crystal. Indium arsenide is used for construction of infrared detectors, for the wavelength range of 1–3.8 µm. The detectors are usually photovoltaicphotodiodes. Cryogenically cooled detectors have lower noise, but InAs detectors can be used in higher-power applications at room temperature as well.
The metal expands when it solidifies, making glass storage difficult. It also attacks most other metals by diffusing into their metal lattice making storage in steel or aluminum containers impossible. Since gallium wets glass and porcelain, it can be used to create brilliant mirrors. Gallium nitrate has even been used in the treatment of arthritis.
Gallium arsenide and gallium phosphide are used in rectifiers and transistors as semiconductors and in lasers, light-emitting transistors, photocells, and electronic refrigeration. Although gallium is widely distributed in nature, it does not occur in appreciable concentrations even in germanite, the ore richest in gallium.
Effective mass and energy band minima and maxima of Ge, Si and GaAs The values of the energy band minima and maxima as well as the effective masses for germanium, silicon and gallium arsenide are listed in the table below:
Gallium Arsenide Microwave Amplifier. This is a Celeritek CTR-990126 CPW microwave transceiver, and there's a stunningly beautiful little city inside. The input and output are not wires: They are waveguides, hollow tubes that the signal travels through as an electromagnetic wave.

Coefficient of Thermal Expansion (CTE) Definition: The coefficient of thermal expansion is defined as the fractional increase in the length per unit rise in temperature. The coefficient of thermal expansion for a material is usually specified over a temperature range because it varies depending on the temperature.
Gallium(III) trioxide is an inorganic compound with the formula Ga 2 O 3.It exists as several polymorphs, all of which are white, water-insoluble solids.Although no commercial applications exist, Ga 2 O 3 is an intermediate in the purification of gallium, which is consumed almost exclusively as gallium arsenide.
Thorlabs stocks a wide selection of photodiodes (PD) with various active area sizes and packages. Discrete PIN junction photodiodes include indium gallium arsenide (InGaAs), gallium phosphide (GaP), and silicon (Si) materials. Germanium (Ge) photodiodes, which are based on an N-on-P structure, are also available.
A compound semiconductor is a semiconductor compound composed of chemical elements of at least two different species. These semiconductors typically form in periodic table groups 13–15 (old groups III–V), for example of elements from the Boron group (old group III, boron, aluminium, gallium, indium) and from group 15 (old group V, nitrogen, phosphorus, arsenic, antimony, bismuth).
Gallium arsenide has a similar structure to silicon and is a useful silicon substitute for the electronics industry. It is an important component of many semiconductors. It is also used in red LEDs (light emitting diodes) because of its ability to convert electricity to light. Solar panels on the Mars Exploration Rover contained gallium arsenide.
