Description

Description The ternary compound bismuth tellurium iodide (BiTeI) is a new class of polar or Janus vdW crystals. They exhibit rather unique structural features, with each layer consisting of Bi atoms sandwiched between tellurium (Te) and iodine (I) atoms. Due to the difference in surface potential within each vdW layer, a large electric field is confined in the layers. This field has been shown to cause the giant Rashba effect, spin-orbit coupling, and spintronic properties.

Features And Benefits

Features And Benefits This layered crystal structure has the triangular space group of P3m1 and lacks spatial inversion symmetry. Our crystals are synthesized using the hierarchical Bridgman growth technique, which is designed for high-purity (99.9999%) vdW crystal growth.

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.
