Bismuth sulfide (Bi₂S₃) Developed at our facilities in the last five (5) years to optimize the perfect stoichiometry. Bi2S3 has layered (lamellar) structure much similar to other 2D crystals such as graphite, MoS2, and Sb2Te3. They can be exfoliated down...

World's largest commercially available electronic grade Bi2Se3 crystals. We offer guaranteed largest undoped or doped Bi2Se3 crystals in the commercial market. Bismuth selenide (Bi2Se3) is a topological insulator crystal belonging to metal chalcogenide...

Bi2SeTe2 is a topological insulator vdW layered crystal. It has the same crystal structure as Bi2Se3 and Bi2Te3, it only differs in that Se and Te atoms are alloyed to retain impressive topological insulator state rivaling to Bi2Te3. Bi2SeTe3 crystal...

We provide the world's largest size commercially available Bi2Te3 crystals at the highest quality Bi2Te3 and affordable prices. Our crystals exceed competing crystals both in size and quality. Description Bismuth Telluride (Bi2Te3) Developed at our...

The ternary compound bismuth telluroiodide (BiTeI) is new class of polar or Janus vdW crystals. They exhibit rather unique structural characteristics in that each layer consists of Bi atoms sandwiched in between tellurium (Te) and iodine (I) atoms as...
