CsInSe2
CsInSe2 is a thermodynamically stable semiconducting compound composed of cesium, indium, and selenium.
About CsInSe2
CsInSe2 is a ternary selenide characterized by its semiconducting electronic nature. As a thermodynamically stable phase located on the convex hull, it represents a robust structural arrangement of cesium, indium, and selenium atoms that maintains integrity under standard conditions. The material is of significant interest in materials science due to its well-defined crystalline configurations. Its stability and semiconducting behavior make it a candidate for fundamental studies into chalcogenide-based electronic components and potential optoelectronic applications.
Key Properties
Cross-validated computational properties for CsInSe2, 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.
