TcB
TcB is a metastable semiconducting compound formed from technetium and boron that is primarily studied for its diverse structural configurations.
About TcB
TcB is a binary compound composed of technetium and boron. As a semiconducting material, it represents a unique intersection of transition metal chemistry and refractory boride structural motifs, drawing significant interest from researchers studying complex phase spaces.
Despite its existence in a large number of reported structural configurations across databases, the compound is characterized as being above the thermodynamic hull. This suggests that while it can be modeled and synthesized under specific conditions, it remains a metastable phase that challenges standard stability expectations.
Key Properties
Cross-validated computational properties for TcB, 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.

How It Compares
As a member of the transition metal boride family, TcB occupies a niche position defined by its semiconducting electronic character. Unlike more common, highly stable refractory borides, TcB exhibits a metastable nature that makes it a compelling subject for studies on high-pressure synthesis and structural phase transitions.
