InLiTe2 is a thermodynamically stable semiconducting material investigated for its potential utility in phase-change memory devices.
About InLiTe2
InLiTe2 is a semiconducting compound belonging to the class of phase-change memory materials. As a thermodynamically stable phase located on the convex hull, it represents a robust candidate for research into switchable electronic states. Its structural characteristics are well-documented across multiple databases, reflecting significant interest in its potential for advanced computing architectures.
This material plays a vital role in the ongoing development of non-volatile memory technologies. By leveraging its semiconducting nature and phase-stability, researchers aim to utilize InLiTe2 to improve the efficiency and reliability of data storage devices that require rapid state transitions.
Key Properties
Cross-validated computational properties for InLiTe2, 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.
