Te3Mo2S
Te3Mo2S is a metastable, semimetallic ternary chalcogenide compound composed of molybdenum, sulfur, and tellurium.

About Te3Mo2S
Te3Mo2S is a complex ternary chalcogenide that exhibits semimetallic electronic behavior. Its near-zero-gap character suggests interesting potential for specialized electronic or optoelectronic applications where traditional semiconductors may not suffice. As a metastable phase, it represents a delicate balance of chemical bonding that is sensitive to synthesis conditions. The existence of multiple reported structures highlights the structural flexibility and complexity inherent in this molybdenum-based system. Researchers study this compound to better understand the phase space of transition metal chalcogenides and to explore the stability limits of such materials. Its unique composition makes it a subject of interest for fundamental materials science investigations into non-equilibrium phases.
Key Properties
Cross-validated computational properties for Te3Mo2S, aggregated across 3 databases.
