Te3Y2
Te3Y2 is a thermodynamically stable semiconducting compound formed from yttrium and tellurium.
About Te3Y2
Te3Y2 is a binary compound composed of tellurium and yttrium that exhibits semiconducting electronic behavior. As a thermodynamically stable phase located on the convex hull, it represents a robust configuration of these elements that has been documented across multiple structural databases. Its stability makes it a compelling subject for researchers investigating the intersection of rare-earth chemistry and chalcogenide semiconductors. The material is characterized by a diverse structural landscape, with several distinct configurations identified in scientific literature. This structural variety suggests that Te3Y2 may possess tunable properties depending on its specific crystalline arrangement, offering potential utility in specialized electronic or optoelectronic applications where stable, semiconducting tellurides are required.
Key Properties
Cross-validated computational properties for Te3Y2, 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.
