In3Se
In3Se is a metallic indium-selenium compound that exists in a metastable state with diverse structural configurations.
About In3Se
In3Se is a metallic compound composed of indium and selenium. As a metallic system, it exhibits conductive behavior distinct from the semiconducting nature often found in related chalcogenides.
Despite its metallic character, the compound is characterized as being above the thermodynamic hull, suggesting it is a metastable phase. Its structural complexity is highlighted by the significant number of reported structures across various materials databases.
Key Properties
Cross-validated computational properties for In3Se, 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.
StabilityA plain-language summary of the best reported energy-above-hull result. It reflects whether the lowest-energy structure is on, near, or far from the stability hull.
