Indium is a very soft, silverywhite, relatively rare true metal with a bright luster. As a pure metal indium emits a highpitched "cry", when it is bent. Both gallium and indium are able to wet glass. One unusual property of indium is that its most common isotope is slightly radioactive; it …
Aluminium gallium indium phosphide (Al Ga In P, also AlInGaP, InGaAlP, GaInP, etc.) is a semiconductor material that provides a platform for the development of novel multijunction photovoltaics and optoelectronic devices, as it spans a direct bandgap from deep ultraviolet to infrared.
InCl3 , in combination with GaCl3, CuCl as Ga, Cu sources, and S2Cl2 and 6%H2 in Ar as reactive gases, was applied as precursor for the Copper indium gallium sulphide Cu(In,Ga)S2 thin films by CVD. The InCl3 and other precursors were liquid inside the furnace and were vaporized with argon carrier gas (50150 sccm), S2Cl2 and 6%H2/Ar were supplied at 250sccm and 350sccm, respectively.
Indium phosphide is like the weird uncle of gallium arsenide. It has some quirks, including being very brittle, and it costs more than GaAs. But some of the highest frequencies of operation reported are on InP, so it will always serve a niche as systems move toward terahertz.

Indium is an ingredient in the gallium–indium–tin alloy galinstan, which is liquid at room temperature and replaces mercury in some thermometers. Other alloys of indium with bismuth, cadmium, lead, and tin, which have higher but still low melting points (between 50 and 100 °C), are used in fire sprinkler systems and heat regulators.
Sep 22, 2019· Indium gallium phosphide (InGaP), also called gallium indium phosphide (GaInP), is a semiconductor composed of indium, gallium and phosphorus. It is used in highpower and highfrequency electronics because of its superior electron velocity with respect to the more common semiconductors silicon and gallium arsenide.
Gallium (Ga), chemical element, metal of main Group 13 (IIIa, or boron group) of the periodic table. It liquefies just above room temperature. Gallium was discovered (1875) by French chemist PaulÉmile Lecoq de Boisbaudran, who observed its principal spectral lines while examining material
Indium is a chemical element. It has the chemical symbol In. It has the atomic number 49. It is a rare metal. It is a soft, malleable and poor metal. Indium looks like zinc. Pieces of indium can easily be joined together by pushing one piece into another. The chemistry of indium is quite like aluminium or gallium. Zinc ores are the main source ...
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 elements of the periodic table while arsenic is a element. Alloys made of these chemical groups are referred to as "IIIV" compounds.
Blood is drawn from a vein, most often on the inside of the elbow or the back of the hand. The site is cleaned with germkilling medicine (antiseptic). The health care provider wraps an elastic band around the upper arm to apply pressure to the area and make the vein swell with blood. Next, the ...

The LEDs provide ultra violet emission based on Indium Gallium Nitride (InGaN) and red, green, blue (RGB) phosphors in the transparent resin, and differ from conventional white LEDs which typically provide blue emission with Yttrium, Aluminum, Garnet (YAG) yellow phosphors.
A copper indium gallium selenide solar cell is a thinfilm solar cell used to convert sunlight into electric power. It is manufactured by depositing a thin layer of copper, indium, gallium and selenium on glass or plastic backing, along with electrodes on the front and back to collect current.

Gallium is the rarest component of new photovoltaic compounds (such as copper indium gallium selenium sulphide or Cu(In,Ga)(Se,S) 2, recently announced by South African researchers) for use in solar panels as an alternative to crystalline silicon, which is currently in short supply. As a wetting, and alloy improvement agent:
Gallium is a chemical element with the symbol Ga and atomic number 31. Elemental gallium is a soft, silvery blue metal at standard temperature and pressure; however in its liquid state it becomes silvery too much force is applied, the gallium may fracture is in group 13 of the periodic table, and thus has similarities to the other metals of the group, aluminium, indium ...
Indium reacts readily with the halogens and (when warm) with other nonmetals, , phosphorus, selenium, and sulfur. It has trivalent compounds that are similar to those of gallium and aluminum. Indium salts color the Bunsen flame a deep blueviolet.

Gallium is a liquid at 30 ° C, so one would expect it to become a solid at ° C. Instead it is fairly easy to cool gallium to below ° C without having it solidify. Gallium's boiling point is about 2,400 ° C (4,400 ° F) and its density is grams per cubic centimeter. Chemical properties. Gallium is a fairly reactive element.
Indium gallium nitride (InGaN, In x Ga 1−x N) is a semiconductor material made of a mix of gallium nitride (GaN) and indium nitride (InN). It is a ternary group III/group V direct bandgap semiconductor. Its bandgap can be tuned by varying the amount of indium in the alloy.
Post transition metals, also known as the poor metals, is a group of metals on the periodic is to the right of the transition Group 12 elements are sometimes included. Sometimes germanium, antimony, and polonium are included, although they are normally considered normally have higher electronegativities than the transition metals.
