· InAgTe2

InAgTe2 is a ternary semiconductor compound combining indium, silver, and tellurium in a chalcogenide crystal structure. This material belongs to the family of III-V and I-III-VI semiconductors, which are of significant interest for optoelectronic and thermoelectric applications. InAgTe2 remains primarily a research-phase compound, but materials in this compositional class are explored for infrared detection, photovoltaic energy conversion, and solid-state cooling due to their tunable bandgap and carrier transport properties.
