PrS2
PrS2 is a stable semiconducting compound formed from praseodymium and sulfur that exhibits diverse structural arrangements.
About PrS2
PrS2 is a stable binary sulfide compound composed of praseodymium and sulfur. As a semiconducting material that resides on the thermodynamic convex hull, it represents a robust phase within the rare-earth chalcogenide family.
Its structural versatility is highlighted by a significant number of reported configurations across major materials databases. This diversity in atomic arrangement makes it a subject of interest for researchers investigating the electronic and magnetic properties of lanthanide-based semiconductors.
Key Properties
Cross-validated computational properties for PrS2, 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.
