Premium Ultra-Flat Sb2S3 Synthetic Crystals

World's first ultra-flat single crystal Sb2S3 measuring more than 3cm in size.

Antimony sulfide is the chemical compound with the formula Sb2S3 which crystallizes in an orthorhombic space group. Sb2S3 shares striking structural and physical similarities with topological insulator Sb2Te3. The orthorhombic phase of Sb2S3 belongs to the space group Pnma (number:62) Recently, Sb2S3 has been shown to exhibit topological state transition under pressure [1]. Sb2S3 crystals exhibit optical band gap at 1.7 -1.8 eV [2] while optical and electronic properties in the monolayer form remain unknown.

Overall characteristics
