As2S3 comes in perfect 2:3 stoichiometry. After 250 growth trials in 3 years, perfect stoichirometry, large domain size, minimal defect density (1 parts in 100,000 unit cells), and perfected purity level (99.9998%) are achieved. In the bulk form,...

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...

BiInTe3 layered crystals crystallize in M2X3 structure where M stands for Bi and In atoms at fixed 50% alloy ratios. BiInTe3 crystals were synthesized using modified Bridgman technique under careful growth condition to ensure there is no phase separation...

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...

BSCCO (Bismuth strontium calcium copper oxide) is a high-temperature layered superconductor. It has the generalized chemical formula Bi2Sr2Can−1CunO2n+4+x, and n=2 which is also known as Bi-2212 with critical temperature (Tc) at ~90-95K. It is...

CdI₂ is a layered semiconductor with indirect gap at 3.0 eV for bulk and its properties in the monolayer form is currently unknown. It crystallizes in generally known as CdI2 crystal structure as shown in the product images. The repeating...

Chromium bromide (CrBr3) is a 2D ferromagnetic semiconductor with a Curie temperature of ~40K. Crystals exhibit perfect 0001 plane orientation as well as perfect in-plane crystallinity as evidenced by XRD and Raman measurements. Layers are largely...

Ternary copper indium selenide crystallizes in CuIn7Se11 stoichiometry to form perfect van der waals (vdW) layered sheets. They are indirect gap semiconductors with high light-matter interaction strength. Because of its high photoresponsivity...

Bulk vdW FeSe crystal is a vdW superconductor with critical tempearture (Tc) of ∼8K. It also exhibits a tetragonal-to-orthorhombic structural transition at Ts~90K. Recently, it has been reported that the FeSe monolayers become superconducting at 65K...
