“Superconducting thin film and high-throughput superconductivity” group (SC2 group of National Lab for Superconductivity) is found in 2014. Prof. Kui Jin is the group leader and the director of National Lab for Superconductivity in IOP, CAS. He also serves as the leader of single-crystalline film experimental station of the Center for Materials Genome, and the leader of “practical superconducting thin film research” group at Songshan Lake Materials Laboratory.

The mechanism of high-temperature superconductivity is the most challenging issue in the field. Building accurate high-dimensional phase diagram and exploring key parameters that determine Tc, would be essential to the comprehension of high-Tc mechanism. The electronic phase diagrams of cuprate superconductors show complexity and diversity, for the strong coupling and interplay among lattice, orbital, charge and spin degrees of freedom. It is tough to construct a high-dimensional holographic phase diagram and obtain quantitative laws by traditional research methods.

Our group are devoted to developing the techniques of epitaxial composition-spread film, in situ continuous manipulation of carriers, as well as corresponding scale-span high-throughput measurement. These high-throughput techniques have been successfully applied in the precise manipulation of chemical composition, lattice, and carrier, accelerating the research on the mechanism from quantitative differences to qualitative ones. The novel high-throughput superconductivity research mode will play an indispensable role in the construction of the high-dimensional holographic phase diagram, the comprehension of high-Tc mechanism, and practical applications of superconductors.
