About HgS4
HgS4 is a distinct semiconducting compound composed of mercury and sulfur. As a thermodynamically stable phase located on the convex hull, it represents a robust structural arrangement that has been identified across numerous documented configurations. Its electronic character suggests potential utility in specialized optoelectronic or sensing technologies where stable semiconducting behavior is required. The material is notable for its structural diversity, supported by a significant body of reported experimental and computational data. This complexity allows researchers to investigate how specific atomic arrangements influence its overall performance in various technical environments.
Key Properties
Cross-validated computational properties for HgS4, aggregated across 2 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.
