C2Cs2
C2Cs2 is an insulating binary compound of carbon and cesium that is typically found in a metastable state.
About C2Cs2
C2Cs2 is a binary compound composed of carbon and cesium that exhibits wide-band-gap insulating behavior. Its electronic structure suggests a highly localized bonding environment typical of insulating materials within this chemical family.
Despite its existence in multiple structural configurations across various databases, the compound is characterized as being above the thermodynamic hull. This indicates that it is likely metastable or unstable under standard conditions, making it a subject of interest for fundamental studies in solid-state chemistry.
Key Properties
Cross-validated computational properties for C2Cs2, 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.
