Antimony triselenide is the chemical compound with the formula Sb2Se3 which crystallizes in an orthorhombic space group. Sb2Se3 shares striking structural and physical similarities with topological insulator Sb2Te3. Recently, Sb2Se3 has been predicted possess topological insulator state[1-3], superconductivity , and high thermoelectric efficiency. Sb2Se3 crystals measure ~1cm in size, rated at 99.9998% purity, and exhibit strong and sharp Raman signal, ideal environmental stability, and high crystalline order. Crystals are synthesized through flux zone technique to high high crystallinity and enable exfoliation.
