About Ce2Cl2Te2
Ce2Cl2Te2 is a complex inorganic compound composed of cerium, chlorine, and tellurium. It exhibits a near-zero-gap electronic structure, placing it in the category of semimetallic materials that bridge the gap between conductors and insulators. Its thermodynamic profile suggests it sits near the stability hull, indicating it is a viable candidate for experimental synthesis and structural characterization. The material's distinct chemical composition allows for unique bonding interactions between the rare-earth metal and the chalcogen-halide framework. This structural arrangement is of significant interest for researchers exploring the electronic properties of ternary halide-chalcogenides. Given its status as a near-hull phase, it represents a promising target for advanced materials development.
Key Properties
