ThSe2
ThSe2 is a stable semiconducting compound composed of thorium and selenium.
About ThSe2
ThSe2 is a binary thorium selenide that exhibits semiconducting electronic behavior. As a thermodynamically stable compound residing on the convex hull, it represents a robust phase within the thorium-selenium chemical system.
Its structural diversity is highlighted by multiple reported configurations across various databases. This complexity makes it an intriguing subject for investigating the interplay between heavy actinide elements and chalcogenides in solid-state chemistry.
Key Properties
Cross-validated computational properties for ThSe2, aggregated across 4 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.
