About Ba2DyInTe5
Ba2DyInTe5 is a complex quaternary telluride belonging to the class of phase-change memory materials. As a semiconducting compound, it exhibits electronic properties that make it a candidate for non-volatile memory applications where rapid structural transitions are required for data storage.
This material is characterized as being near-hull in terms of thermodynamic stability, suggesting it is a viable candidate for experimental synthesis. Its unique chemical composition involving barium, dysprosium, indium, and tellurium positions it as an intriguing subject for research into next-generation chalcogenide-based electronics.
Key Properties
Cross-validated computational properties for Ba2DyInTe5, 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.
Unlike the industry-standard phase-change materials such as Ge2Sb2Te5 or Sb2Te3, which are binary or ternary systems often optimized for rapid crystallization, Ba2DyInTe5 introduces rare-earth dysprosium into the lattice. This structural complexity differentiates it from simpler tellurides like Ag2Te or In2Te3, potentially offering unique switching characteristics or improved thermal stability profiles for specialized memory architectures.
