Description
FeSe0.65Te0.35 is a member of the iron-based chalcogenide superconductors, exhibiting a layered crystal structure with weak van der Waals interlayer coupling. This composition is widely regarded as the optimal stoichiometry in the FeSe₁₋ₓTeₓ system, offering the highest bulk critical temperature (~14–15 K), excellent phase purity, and robust superconducting behavior. Structurally, FeTeSe consists of iron atoms in a square lattice sandwiched by chalcogen (Se/Te) layers, arranged in the P4/nmm space group, similar to other layered materials like graphene and MoS2.
These high-quality, flux-grown FeSe0.65Te0.35 crystals are synthesized and characterized in our state-of-the-art facilities. Each crystal is verified for superconductivity, phase purity, and surface quality. The material is readily exfoliable, making it ideal for monolayer studies and heterostructure engineering.
