Sb₂Te (Antimony Telluride)

Sb₂Te is an antimony-rich phase in the Sb–Te system, with a composition far from the stoichiometric Sb₂Te₃. It serves as a reference composition for phase-change memory research and for studies of antimony-rich thermoelectric alloys.

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: Difficult — not a van der Waals layered phase, so mechanical exfoliation is challenging.
