Name: Iron Selenide (FeSe)
SKU: ACMA00022875
Rating: 5 (1 reviews)

Description

Description Bulk vdW FeSe crystals are vdW superconductors with a critical temperature (Tc) of about 8K. It also exhibits a tetragonal-to-orthogonal structural transition at Ts ~90K. We synthesized crystals within 4 months using the Bridgman technique to achieve large single domain size, single crystallinity, and high purity.

Features And Benefits

Features And Benefits A single FeSe sheet consists of successively stacked FeSe layers with a square lattice layer of iron atoms sandwiched between two sparser layers of bonded chalcogenide atoms in the P4nmm space group.
The crystals are close to 4-6 mm in size and they are perfectly oriented in the 0001 direction, allowing tape stripping without any complex stripping techniques such as liquid phase or electrochemical methods.

Application

Application New 2D semiconductors, topological insulators, and superconductors have numerous applications in advanced technologies, and Alfa Chemistry engineers can guide customers in material characterization and selection.
