Sb1.75Bi0.25Te3 Crystal

World's only commercially topological and thermoelectric engineered SbBiTe3 crystals

Sb1.75Bi0.25Te3 is a layered van der Waals alloy within the tetradymite family of topological and thermoelectric materials. Partial substitution of Bi into the Sb2Te3 lattice enables tuning of carrier concentration, electronic band structure, and phonon transport. The resulting alloy exhibits reduced lattice thermal conductivity through enhanced phonon scattering while maintaining favorable electrical transport properties, making it attractive for thermoelectric energy conversion, topological materials research, and electronic device applications.

Our Sb1.75Bi0.25Te3 crystals are grown by the Bridgman method using high purity precursor materials to produce large, highly crystalline single crystals with excellent compositional uniformity and clean cleavage surfaces. The crystals are suitable for exfoliation, transport measurements, spectroscopy, thermoelectric studies, and topological quantum materials research.

Crystal measures around 5-7 mm in size.
