· Ge4 Ru4

Ge₄Ru₄ is an intermetallic semiconductor compound combining germanium and ruthenium in a 1:1 atomic ratio. This material exists primarily in research contexts as part of the broader family of transition metal-germanium compounds, which are investigated for their unique electronic and structural properties. The combination of a semi-metal (ruthenium) with a semiconductor (germanium) creates a system of scientific interest for exploring novel band structures and potential quantum phenomena.
