About Ultra Thin Selenium Nanoscale Foil

American Elements’ Nanometal™ Nanoscale Foil manufacturing unit produces ultra thin foil as thin as only 50 nm thick in diameters up to 910 mm. Typically, foils are in thicknesses from 20 nm to 1000 nm, 1 micron, 2 micron, and up to a few microns thick. Nanometal™ ultra thin foil can also be produced on a substrate with a parting agent to permit removal by floating and can then be mounted on frames. Frames may be washers, rings, or more-complicated assemblies. Nanometal™ is one of the many ultra high purity metal forms available from American Elements for semiconductor and other electronic applications and for use in coating and thin film Chemical Vapor Deposition (CVD) and Physical Vapor Deposition (PVD) processes including Thermal and Electron Beam (E-Beam) Evaporation, Low Temperature Organic Evaporation, Atomic Layer Deposition (ALD), Organometallic and Chemical Vapor Deposition (MOCVD) in specific applications such as fuel cells and solar energy. We also produce metallic nanopowders (see also Nanotechnology) and metals by crystallization for this purpose. For foils >1 micron thick see our Selenium Foil page. We also produce Selenium as rods, powder and plates. Other shapes are available by request.

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.
