About Copper Gallium Selenide Sputtering Target

Copper Gallium Selenide for solar energy applications is a p-type or absorber layer material. American Elements specializes in producing high purity Copper Gallium Selenide Sputtering Targets with the highest possible density High Purity (99.99%) Copper Gallium Selenide Sputtering Targetand smallest possible average grain sizes for use in semiconductor, chemical vapor deposition (CVD) and physical vapor deposition (PVD) display and optical applications. Our standard Sputtering Targets for thin film are available monoblock or bonded with planar target dimensions and configurations up to 820 mm with hole drill locations and threading, beveling, grooves and backing designed to work with both older sputtering devices as well as the latest process equipment, such as large area coating for solar energy or fuel cells and flip-chip applications. We offer all shapes and configurations of targets compatible with all standard guns including circular, rectangular, annular, oval, "dog-bone," rotatable (rotary), multi-tiled and others in standard, custom, and research sized dimensions. All targets are analyzed using best demonstrated techniques including X-Ray Fluorescence (XRF), Glow Discharge Mass Spectrometry (GDMS), and Inductively Coupled Plasma (ICP). "Sputtering" allows for thin film deposition of an ultra high purity sputtering metallic or oxide material onto another solid substrate by the controlled removal and conversion of the target material into a directed gaseous/plasma phase through ionic bombardment. Materials are produced using crystallization, solid state and other ultra high purification processes such as sublimation. American Elements specializes in producing custom compositions for commercial and research applications and for new proprietary technologies. American Elements also casts any of the rare earth metals and most other advanced materials into rod, bar, or plate form, as well as other machined shapes and through other processes such as nanoparticles and in the form of solutions and organometallics. We also produce Copper as disc, granules, ingot, pellets, pieces, powder, and rod. Other shapes are available by request.

The number of electrons in each of copper's shells is 2, 8, 18, 1 and its electron configuration is [Ar]3d10 4s1. The copper atom has a radius of 128 pm and a Van der Waals radius of 186 pm. Copper was first discovered by Early Man prior to 9000 BC. In its elemental form, copper has a reddish-orange metallic and lustrous appearance. Of all pure metals, only silver Elemental Copperhas a higher electrical conductivity. The origin of the word copper comes from the Latin word 'cuprium' which translates as "metal of Cyprus," as the Mediterranean island of Cyprus was known as an ancient source of mined copper..

Gallium (atomic symbol: Ga, atomic number: 31) is a Block P, Group 13, Period 4 element with an atomic weight of 69.723.The number of electrons in each of Gallium's shells is 2, 8, 18, 3 and its electron configuration is [Ar] 3d10 4s2 4p1. The gallium atom has a radius of 122.1 pm and a Van der Waals radius of 187 pm. Gallium Bohr ModelGallium was predicted by Dmitri Mendeleev in 1871. It was first discovered and isolated by Lecoq de Boisbaudran in 1875. In its elemental form, gallium has a silvery appearance. Elemental GalliumGallium is one of three elements that occur naturally as a liquid at room temperature, the other two being mercury and cesium. Gallium does not exist as a free element in nature and is sourced commercially from bauxite and sphalerite. Currently, gallium is used in semiconductor devices for microelectronics and optics. The element name originates from the Latin word 'Gallia' referring to Gaul, the old name of France.


Selenium Bohr ModelSee more Selenium products. Selenium (atomic symbol: Se, atomic number: 34) is a Block P, Group 16, Period 4 element with an atomic radius of 78.96. The number of electrons in each of Selenium's shells is 2, 8, 18, 6 and its electron configuration is [Ar] 3d10 4s2 4p4. The selenium atom has a radius of 120 pm and a Van der Waals radius of 190 pm. Selenium is a non-metal with several allotropes: a black, vitreous form with an irregular crystal structure three red-colored forms with monoclinic crystal structures and a gray form with a hexagonal crystal structure, the most stable and dense form of the element. Elemental SeleniumOne of the most common uses for selenium is in glass production the red tint that it lends to glass neutralizes green or yellow tints from impurities in the glass materials. Selenium was discovered and first isolated by Jöns Jakob Berzelius and Johann Gottlieb Gahn in 1817. The origin of the name Selenium comes from the Greek word "Selênê," meaning moon.
