The equilibrium geometries of embedded binary eutectic alloy nanostructures are used to determine the interfacial free energies between two phases of a strongly segregating alloy and the matrix. The solid Ge-SiO2 interfacial free energy at 600°C is determined to be 0.82–0.99 J/m2, in good agreement with estimates obtained from stress relaxation experiments.
