Ruthenium oxide has attracted recent interest as a non-superconducting material where superconductivity can be induced by epitaxial strain. Here, the authors explore strained (100)-oriented RuO2 films on TiO2(100) substrate and reveal strain-induced superconductivity similarly to strained RuO2(110) films, providing insights into the thickness-dependence and electronic structure mechanisms of superconductivity.
