· JVASP-35541· NbTl3Se4

NbTl3Se4 is an intermetallic compound combining niobium, thallium, and selenium, representing a ternary metal-based material from the transition metal chalcogenide family. This is a research-phase compound not yet established in mainstream industrial production; materials in this compositional space are primarily investigated for their potential electronic and thermal properties in condensed matter physics and materials discovery programs. The material's relevance lies in fundamental studies of electronic structure, superconductivity screening, and thermoelectric applications, where the combination of heavy elements and layered chalcogenide chemistry offers potential for unusual transport phenomena.
