· Er2 Pd1 Au1

Er₂Pd₁Au₁ is a ternary intermetallic compound combining erbium (a rare-earth element), palladium, and gold in a 2:1:1 stoichiometric ratio. This is a research-phase material studied primarily for its potential in thermoelectric and electronic applications, leveraging the unique electron-scattering and phonon-transport properties that arise from combining rare-earth and noble-metal constituents. While not yet established in volume production, materials in this family are of interest for high-temperature energy conversion and specialized microelectronic or optoelectronic devices where rare-earth–noble-metal interactions offer advantages over conventional binary alloys.
