Sb₂S₃ (Antimony Sulfide)

Sb₂S₃ is a layered orthorhombic semiconductor (Pnma), isostructural with Bi₂S₃, with a band gap near 1.7 eV. It is a promising absorber for thin-film photovoltaics and a candidate phase-change material.

Growth method: Chemical vapor transport (CVT).

Sample specifications: Individual crystals measure approximately 3–4 mm, with a purity of up to 99.999% (5N), and 2–3 high-quality single-crystal pieces included in each package.

Exfoliation: Moderate — cleaves along the layers into thin ribbons and flakes.
