American Elements specializes in producing high purity Copper(I) Telluride Sputtering Targets with the highest possible density High Purity (99.99%) Copper(I) Telluride 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 deposition 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. Rotary (cylindrical), round, rectangular, square, ring, annular, oval, "dog-bone" and other shaped targets are available 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). 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.

See more Copper products. Copper Bohr Model Copper (atomic symbol: Cu, atomic number: 29) is a Block D, Group 11, Period 4 element with an atomic weight of 63.546. 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 red-orange metallic luster 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." Cyprus, a Mediterranean island, was known as an ancient source of mined copper.

See more Tellurium products. Tellurium (atomic symbol: Te, atomic number: 52) is a Block P, Group 16, Period 5 element with an atomic radius of 127.60. Tellurium Bohr ModelThe number of electrons in each of tellurium's shells is 2, 8, 18, 18, 6 and its electron configuration is [Kr] 4d10 5s2 5p4. Tellurium was discovered by Franz Muller von Reichenstein in 1782 and first isolated by Martin Heinrich Klaproth in 1798. In its elemental form, tellurium has a silvery lustrous gray appearance. The tellurium atom has a radius of 140 pm and a Van der Waals radius of 206 pm. Elemental TelluriumTellurium is most commonly sourced from the anode sludges produced as a byproduct of copper refining. The name Tellurium originates from the Greek word Tellus, meaning Earth.
