HCaGaSi
HCaGaSi is a metastable semiconducting quaternary hydride being studied for its potential role in advanced hydrogen storage technologies.
About HCaGaSi
HCaGaSi is a complex semiconducting hydride that represents a niche category of materials designed for hydrogen storage. Its metastable nature suggests a delicate balance in its atomic configuration, which is of significant interest for researchers exploring new pathways for reversible gas uptake and release.
As a quaternary hydride, it occupies a specialized space in materials science where the integration of calcium, gallium, and silicon creates a unique electronic environment. This structural complexity is essential for understanding how hydride materials can be tuned to improve hydrogen density and kinetic performance in energy storage systems.
Key Properties
Cross-validated computational properties for HCaGaSi, 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
Within the hydrogen storage hydrides class.
Unlike simple binary hydrides such as MgH2 or LiH, which are well-established benchmarks for hydrogen storage, HCaGaSi represents a more complex, multi-element approach to the field. While traditional hydrides like CaH2 are often utilized for their robust stability, HCaGaSi offers a distinct, metastable semiconducting framework that differentiates it from the more conventional, ionic-bonded members of this class.
