Ge1Li1Te2
Ge1Li1Te2 is a semiconducting telluride compound investigated for its potential utility in phase-change memory applications.
About Ge1Li1Te2
Ge1Li1Te2 is a semiconducting material belonging to the phase-change memory class. Its structural characteristics and near-hull thermodynamic stability suggest it is a viable candidate for synthesis and integration into advanced electronic devices.
As a member of the telluride-based memory material family, it plays a role in the ongoing research into materials that can undergo rapid, reversible transitions between amorphous and crystalline states. This property is essential for developing high-density, non-volatile memory technologies that require fast switching speeds.
Key Properties
Cross-validated computational properties for Ge1Li1Te2, aggregated across 2 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.
StabilityA plain-language summary of the best reported energy-above-hull result. It reflects whether the lowest-energy structure is on, near, or far from the stability hull.
