We report the integration of SrRuO₃, one of the most widely used oxide electrode materials in functional oxide heterostructures, with silicon using molecular-beam epitaxy and an SrTiO₃ buffer layer. The resulting SrRuO₃ film has a rocking curve full width at half maximum of 0.01°, a resistivity at room temperature of 250 μΩ cm, a residual resistivity ratio (ρ₃₀₀ K/ρ₄ K) of 11, and a paramagnetic-to-ferromagnetic transition temperature of ~160 K. These structural, electrical, and magnetic properties compare favorably to the best reported values for SrRuO₃ films on silicon and rival those of epitaxial SrRuO₃ films produced directly on SrTiO₃ single crystals by thin film growth techniques other than molecular-beam epitaxy. These high quality SrRuO₃ films with metallic conductivity on silicon are relevant to integrating multi-functional oxides with the workhorse of semiconductor technology, silicon.
