Tc4 is a thermodynamically stable metallic compound consisting of technetium atoms.
About Tc4
Tc4 is a metallic compound composed entirely of technetium atoms. As a thermodynamically stable phase located on the convex hull, it represents a robust structural arrangement for this rare transition metal. Its metallic nature suggests high electrical conductivity, making it an interesting subject for fundamental studies in heavy metal bonding and crystal lattice stability. Given the significant number of reported structures across multiple databases, this compound serves as a key reference point for understanding the complex phase behavior of technetium. It is primarily utilized in experimental materials science to map the structural landscape of transition metal clusters and to investigate the unique properties of technetium-based systems in extreme environments.
Key Properties
Cross-validated computational properties for Tc4, aggregated across 4 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.
