A doubling of the superconducting transition temperature occurs in strained SrTiO 3 films, which are known to become ferroelectric. The nature of superconductivity in SrTiO 3 , the first oxide superconductor to be discovered, remains a subject of intense debate several decades after its discovery. S...
