Environmentally stable anisotropic transition metal trichalcogenide material ZrS₃ is available at 2Dsemiconductors USA. ZrS₃ is a layered material like MoS₂ and other layered systems, except that it exhibits highly anisotropic crystalline structure and material properties (Like ReS₂ or TiS₃). The presence of the crystalline anisotropy results in direction dependent properties like thermal conductivity, electronic mobility, and excitonic binding energies. In a typical order, a large number of layered needle like sheets are contained in a capsule sealed under Argon environment. Crystals have been characterized by TEM, XPS, SIMS, Raman, and XRD and possess perfect 1:3 stoichiometry and defect density less than 1 defects / 10,000 unit cells.

Crystal size ~ 0.4-0.6 cm
