SnC
SnC is a semiconducting tin-carbon compound primarily studied for its structural diversity and potential applications in advanced electronic materials.
About SnC
SnC is a binary compound composed of tin and carbon. As a semiconducting material, it represents an interesting intersection of group 14 elements, drawing significant interest from researchers investigating novel thin-film architectures and potential electronic components.
Despite its academic interest, the compound is characterized by its position above the thermodynamic hull, suggesting it is a metastable phase. Its status as a highly studied material is reflected in the extensive number of structural configurations reported across various computational databases.
Key Properties
Cross-validated computational properties for SnC, 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.
StabilityA plain-language summary of the best reported energy-above-hull result. It reflects whether the lowest-energy structure is on, near, or far from the stability hull.
