CrPS3
CrPS3 is a metastable, semimetallic ternary sulfide that serves as an intriguing subject for research into the electronic properties of complex chalcogenides.
About CrPS3
CrPS3 is a complex ternary sulfide characterized by its near-zero-gap electronic structure. Its composition suggests a semimetallic nature, placing it in a unique position among transition metal-based chalcogenides where electronic behavior is highly sensitive to atomic arrangement.
Due to its position above the thermodynamic hull, this compound is considered metastable, which presents significant challenges for synthesis and long-term stability. Despite these hurdles, it remains a subject of interest for researchers investigating the limits of phase stability in layered-type inorganic materials.
Key Properties
Cross-validated computational properties for CrPS3, 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.
