HfTiO4
HfTiO4 is a metastable semiconducting oxide containing hafnium and titanium used in research for electronic and dielectric applications.
About HfTiO4
HfTiO4 is a ternary oxide composed of hafnium, titanium, and oxygen. As a semiconducting material, it represents an interesting subject for research into dielectric and electronic thin-film technologies where precise control over stoichiometry and phase stability is required. Because it exists in a metastable state, its synthesis often requires careful processing to stabilize the desired crystalline form. The existence of multiple reported structures highlights its structural flexibility and the ongoing interest in characterizing its behavior for potential integration into next-generation devices.
Key Properties
Cross-validated computational properties for HfTiO4, 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.
