· Ge2 Er2

Ge₂Er₂ is an experimental intermetallic compound combining germanium and erbium, belonging to the rare-earth germanide family of semiconductors. This material is primarily investigated in research contexts for potential applications in optoelectronics and thermoelectric devices, where the combination of a Group IV element with a lanthanide rare-earth element offers tunable electronic properties and potential phonon-scattering advantages over conventional semiconductors.
