Ag2Ba2Te6Y2
Ag2Ba2Te6Y2 is a stable, semiconducting quaternary telluride used in the study and development of advanced phase-change memory technologies.
About Ag2Ba2Te6Y2
Ag2Ba2Te6Y2 is a complex, thermodynamically stable quaternary chalcogenide that functions as a semiconductor. Its position on the convex hull indicates high structural integrity, making it a subject of significant interest for researchers investigating new phase-change memory architectures. The material is characterized by its distinct atomic arrangement, which allows for the rapid, reversible transitions between amorphous and crystalline states required for non-volatile memory devices. Its unique composition of silver, barium, tellurium, and yttrium provides a specialized electronic profile compared to simpler binary chalcogenides.
Key Properties
Cross-validated computational properties for Ag2Ba2Te6Y2, 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.

How It Compares
Within the phase-change memory materials class.
Within the broader family of phase-change memory materials, Ag2Ba2Te6Y2 offers a more complex structural landscape than standard binary compounds like Ag2Te or AgTe. While materials such as Ge2Sb2Te5 remain the industry standard for phase-change applications, the inclusion of yttrium and barium in this quaternary system allows for fine-tuning of the electronic properties, potentially offering enhanced stability or switching characteristics compared to more traditional telluride-based systems.
