About In2Na2Te4
In2Na2Te4 is a semiconducting compound within the phase-change materials family. As a thermodynamically stable phase located on the convex hull, it represents a well-defined structural configuration that is of significant interest for understanding phase-transition dynamics in complex chalcogenide systems.
This material is primarily studied for its potential utility in non-volatile memory technologies. Its electronic properties and structural stability make it a subject of investigation for researchers looking to optimize switching performance and data retention in advanced computing architectures.
Key Properties
Cross-validated computational properties for In2Na2Te4, 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.
Compared to widely utilized phase-change materials like Ge2Sb2Te5 or the binary Sb2Te3, In2Na2Te4 offers a distinct chemical composition that expands the design space for phase-change memory. While many siblings in this class rely on germanium or antimony to facilitate rapid structural switching, the inclusion of sodium and indium provides a unique electronic environment that differentiates its transition characteristics from traditional telluride-based alloys.
