In4Se3 is a semiconducting indium selenide compound that is considered stable enough to be synthesized for research and potential technological use.
About In4Se3
In4Se3 is a semiconducting compound composed of indium and selenium. Its electronic character positions it as a candidate for specialized semiconductor applications where specific charge transport properties are required.
As a near-hull material, In4Se3 is considered likely to be synthesizable under controlled conditions. The existence of multiple reported structures across various databases highlights its structural complexity and the ongoing interest in its phase stability.
Key Properties
Cross-validated computational properties for In4Se3, aggregated across 3 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.

Reported Structures
Lowest-energy structures reported for In4Se3, ranked by energy above hull.
| Space GroupSymmetry classification of the crystal arrangement. The number is the international space-group index. | Crystal SystemBroad lattice family, such as cubic, tetragonal, monoclinic, or triclinic, derived from unit-cell symmetry. | Band Gap (eV)Electronic gap calculated for this specific reported structure, measured in electronvolts. | E above hull (eV/atom)Thermodynamic distance from the convex hull for this structure, normalized per atom. Lower is generally more stable. | E/atom (eV)Computed total energy normalized per atom.
