SnTe3
SnTe3 is a metallic tin-telluride compound known for its structural diversity and metastable nature.
About SnTe3
SnTe3 is a metallic tin-telluride compound characterized by its distinct electronic properties. As a material that lacks a band gap, it exhibits conductive behavior typical of metallic systems, making it an interesting subject for fundamental condensed matter research.
Despite its existence in multiple structural configurations across various databases, the compound is considered thermodynamically unstable. Its position above the energy hull suggests that while it can be synthesized in specific conditions, it remains a metastable phase of interest for studying tin-tellurium bonding dynamics.
Key Properties
Cross-validated computational properties for SnTe3, aggregated across 5 databases.
Band GapEnergy needed to move an electron from the valence band to the conduction band. Lower or zero values tend to behave more metallic; larger gaps are more insulating or semiconducting.
Energy Above HullThermodynamic distance from the most stable set of competing phases. 0 eV/atom is on the convex hull; small positive values may still be experimentally accessible.
