Pr2Rb2Te8
Pr2Rb2Te8 is a thermodynamically stable semiconducting quaternary telluride containing praseodymium, rubidium, and tellurium.
About Pr2Rb2Te8
Pr2Rb2Te8 is a complex quaternary telluride that sits firmly on the convex hull, indicating significant thermodynamic stability. As a semiconducting material, it offers a unique electronic profile defined by the interplay between the rare-earth praseodymium, alkali rubidium, and chalcogen tellurium elements.
This compound is of interest to researchers investigating novel chalcogenide frameworks. Its structural complexity and stable nature make it a compelling candidate for fundamental studies in solid-state chemistry and materials science, particularly where specific electronic band characteristics are required.
Key Properties
Cross-validated computational properties for Pr2Rb2Te8, 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.
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.
