· Cu1 Ge1 Yb1

CuGeYb is an intermetallic compound combining copper, germanium, and ytterbium in a 1:1:1 stoichiometry. This is a research-phase semiconductor material being investigated for thermoelectric and electronic applications, where the rare-earth ytterbium component is expected to modulate electrical and thermal transport properties. The compound represents an emerging class of multi-principal element semiconductors designed to achieve improved performance in energy conversion and solid-state device contexts where conventional binary or ternary compounds fall short.
