“…RuO 2 with the rutile structure is well known to be a highly conducting binary oxide [12,13]. RuO 2 finds many engineering applications in electrodes, thermometers, and also catalysts, and thin films, mostly polycrystalline films, have been prepared for such purposes by various growth methods [14][15][16][17][18][19][20][21][22][23][24]. In recent years, on the other hand, RuO 2 has attracted renewed attention as a high-temperature antiferromagnet [25,26] and a possible topological nodal line semimetal [27,28], demanding reexamination of its electronic transport in the ground state.…”

We report strain engineering of superconductivity in RuO 2 singlecrystalline films, which are epitaxially grown on rutile TiO 2 and MgF 2 substrates with various crystal orientations. Systematic mappings between the superconducting transition temperature and the lattice parameters reveal that shortening of specific ruthenium-oxygen bonds is a common feature among the superconducting RuO 2 films. Ab initio calculations of electronic and phononic structures for the strained RuO 2 films suggest the importance of soft phonon modes for emergence of the superconductivity. The findings indicate that simple transition metal oxides such as with the rutile structure may be suitable for further exploring superconductivity by controlling phonon modes through the epitaxial strain.
