ReS₂ Crystals

ReS₂ Crystals

ReS₂ (Rhenium Disulfide) is a layered transition metal dichalcogenide (TMD) with a unique distorted 1T phase structure, exhibiting in-plane anisotropy, strong spin-orbit coupling, and highly tunable electronic and optical properties. Unlike conventional TMDs with hexagonal symmetry, ReS₂ features a triclinic crystal structure that results in highly anisotropic transport and optical responses. It is an ideal material for applications in optoelectronics, anisotropic electronics, nonlinear optics, and 2D material research. Our ReS₂ crystals are synthesized using the Chemical Vapor Transport (CVT) method, ensuring high purity, excellent crystallinity, and precise stoichiometry.
