Abstract:The discovery of the interface‐enhanced superconductivity in the single‐layer film of FeSe epitaxially grown on SrTiO3 substrates has triggered a flurry of activity in the field of superconductivity. It raised the hope to find more conventional high transition temperature (Tc) superconductors that are purely driven by the electron‐phonon interaction at ambient pressure. Here the epitaxial growth of the Pb nano‐sized islands on SrTiO3 (001) substrates with the island volumes ranging from 286 to 4945 nm3 is repo… Show more
