BaSbTe3
BaSbTe3 is a thermodynamically stable semiconducting chalcogenide used in the development of advanced phase-change memory technologies.
About BaSbTe3
BaSbTe3 is a semiconducting ternary chalcogenide that sits firmly on the convex hull, indicating notable thermodynamic stability. As a member of the phase-change memory material class, it possesses the structural characteristics necessary to undergo reversible transitions between amorphous and crystalline states, which is fundamental for high-density data storage applications. Its unique composition of barium, antimony, and tellurium allows for distinct electronic behavior compared to more traditional binary systems. This stability makes it an intriguing candidate for research into durable, long-lasting memory devices that require reliable switching performance over numerous cycles. By leveraging its specific electronic character, engineers can explore new pathways for optimizing the energy efficiency and speed of next-generation non-volatile memory architectures.
Key Properties
Cross-validated computational properties for BaSbTe3, 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.
