Fe4Rb12S12
Fe4Rb12S12 is a thermodynamically stable, semimetallic iron-rubidium sulfide compound.
About Fe4Rb12S12
Fe4Rb12S12 is a complex ternary sulfide composed of iron, rubidium, and sulfur. As a thermodynamically stable phase residing on the convex hull, it represents a robust structural arrangement within its chemical system. Its electronic character is defined as a near-zero-gap semimetal, suggesting interesting conductive properties that bridge the gap between traditional metallic and semiconducting materials.
The compound is notable for its structural diversity, supported by multiple reported entries across major materials databases. This stability and electronic profile make it a subject of interest for researchers investigating the interplay between transition metals and alkali-rich chalcogenide frameworks in solid-state chemistry.
Key Properties
Cross-validated computational properties for Fe4Rb12S12, aggregated across 3 databases.
