About Cd4Te3Se
Cd4Te3Se is a complex chalcogenide semiconductor composed of cadmium, tellurium, and selenium. Its electronic properties make it a subject of interest for researchers exploring tunable materials for light-sensitive technologies. The compound is characterized by its near-hull thermodynamic stability, suggesting that it is a viable target for experimental synthesis and structural characterization. With multiple reported structures across databases, it remains a significant entry in the study of cadmium-based ternary and quaternary systems. Its potential for integration into semiconductor devices relies on the precise control of its stoichiometry and crystalline arrangement.
Key Properties
Cross-validated computational properties for Cd4Te3Se, 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.
