About AsKO5Ti
AsKO5Ti is a complex oxide belonging to the class of lead-free piezoelectric materials. As a wide-band-gap insulator, it exhibits robust electronic properties that make it a subject of interest for researchers seeking environmentally friendly alternatives to traditional lead-based ceramics. Its position on the convex hull confirms that it is a thermodynamically stable phase, suggesting potential for reliable synthesis and long-term functional performance.
This compound represents an intriguing addition to the landscape of functional oxides, where the integration of arsenic, potassium, and titanium creates a unique crystalline architecture. Its insulating nature is critical for its role in piezoelectric applications, where minimizing leakage current is essential for maintaining high efficiency in sensing and actuation devices.
Key Properties
Cross-validated computational properties for AsKO5Ti, 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.
