Y(CuSe)3

Y(CuSe)₃ is a ternary semiconductor compound combining yttrium, copper, and selenium in a 1:3:3 stoichiometric ratio. This material belongs to the family of mixed-metal chalcogenides and is primarily studied as a research compound for potential optoelectronic and thermoelectric applications, though it remains largely in the experimental phase without established large-scale industrial production. The yttrium-copper-selenium system is of interest to researchers investigating new semiconductor architectures for photovoltaic devices, photodetectors, and thermal energy conversion, where the combination of rare-earth and transition-metal elements may enable tunable electronic properties and band structures not easily achieved in conventional binary semiconductors.
