About 2D Tellurene Crystals

Tellurene is a novel two dimensional (2D) material composed of stacked layers of tellurium atoms arranged in a trigonal crystal lattice. American Elements manufactures Tellurene Crystals as part of its comprehensive catalog of 2D materials including transition metal dichalcogenides (TMDCs) and trichalcogenides (TMTCs), MXenes, and nanomaterials such as graphene. Materials are produced with ultra high purities (≥99.999%) via crystal growth techniques such as chemical vapor transport (CVT), flux transport, or Czochralski pulling. Novel 2D semiconductors and topological insulators have numerous applications in advanced technologies and American Elements engineers can provide guidance to customers on materials characterization and selection. Powders and other forms may be available by request. Please request a quote above to receive pricing information based on your specifications.

Tellurium

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.
