Description
Bismuth telluride (BiTe) is an intermediate composition material in Bismuth chalcogen material family. It exhibits rather unusual material properties including topological response, low temperature superconductivity, semimatellicity, as well as CDWs. Bismuth telluride is one of our latest addition to 2D metals family. BiTe has also been theoretically predicted and recently experimentally demonstrated to be 2D thermoelectric material [1,2]. BiTe crystals come at perfect 001 orientation ready for mechanical exfoliation. Crystals are rated at 99.9999% (6N electronic grade purity) which is ideal for research purposes.
