PACRIM S30: High Temperature Superconductors: Materials, Technologies, and Systems

The discovery of superconductivity in cuprates, pnictides, and related materials generated an outburst of research activity and exciting new discoveries—most recently in bilayer graphene and infinite-layer nickelates. However, a key challenge remains: the understanding of mechanisms of unconventional superconductivity, still under debate despite many relevant advances in research and materials development. Meanwhile, many new superconductors have emerged, including ruthenates, cobaltates, borides, borocarbides, doped fullerenes, intercalated graphite, hydrides, sulphites, and organic and heavy-fermion superconductors; accompanied by in-depth characterization of their physical properties via a variety of experimental approaches and successful applications in wires, tapes, processing in electronics, and novel nano-related technologies like nano-engineering.

This symposium follows the scheme of similar ceramics and materials-related symposia: It will highlight discoveries of new superconductors, as well as progress in fundamental and technological studies of already known materials and phenomena. The focus will be on novel aspects, issues and systems, yet attention will also be paid to all superconducting-related topics, including fundamental aspects of theory, advances in synthesis, functionalization and processing, and the latest progress in areas of the field effect, thin-film heterostructures, and novel devices at both small and large scale ranges, including new applications in quantum devices.
