ScTc2
ScTc2 is a thermodynamically stable metallic intermetallic compound formed from scandium and technetium.

About ScTc2
ScTc2 is a metallic compound composed of scandium and technetium. As a thermodynamically stable phase located on the convex hull, it represents a robust structural arrangement of these transition metals. The material exhibits characteristic metallic electronic behavior, lacking a band gap, which is typical for intermetallic phases of this nature. Its presence in multiple structural databases highlights its significance in fundamental materials science research. Given its stable configuration, it serves as an important subject for studying the interactions between group three and group seven transition elements. Researchers often investigate such compounds to better understand the phase stability and electronic properties of complex binary metal systems.
Key Properties
Cross-validated computational properties for ScTc2, 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.
