YAgSe2

YAgSe₂ is an intermetallic compound combining yttrium, silver, and selenium in a layered crystal structure, representing an emerging material in the rare-earth metal family with potential semiconducting or semimetallic properties. This material remains largely in the research phase, with study focused on understanding its electronic and mechanical behavior for next-generation applications requiring combination of rare-earth stability and noble-metal conductivity. Its yttrium-silver-selenium composition positions it as a candidate for specialty electronics, thermoelectric systems, or photonic devices where conventional alloys prove insufficient.
