Search for Very-High Temperature Superconductivity and Re-Entrant Superconductivity in Oxy-Chalcogenides
Abstract
The research aimed in advancing properties of materials to far exceed the currently achievable level was always one of the priorities of the DoD 6.1 research. In addition to human enthusiasm and skills, such a research requires advanced instrumentation which is impossible to acquire within a single-investigator grant. Hereby we request funds for acquisition of system of instrumentation essentially contributing and enhancing the quality of research and research-related education currently funded by the ONR (Grant # N00014-15-1-2095, PI Dr. A. Gulian). This research is related to the pursuit of superconductors with the critical temperatures close to the room level. The problem is extremely hard and requires non-standard approaches. In our case it is based on synthesis in conditions of non-equilibrium phase diagrams. The results are important for DoD, and the world competition is very strong. The set of instrumentation requested will help to accelerate the domestic progress in superconducting materials, to make the results more reliable and far reaching. In addition to the existing equipment and facilities, the requested instrumentation will also establish new capabilities for performing research and research-related education in the area of quantum devices for superconducting electronics, with a direct interest to the DoD needs. The system of equipment consists of tools for certification of unusual superconducting phases (via heat capacity measurements) which are expected to have complex character in conditions of non-equilibrium phase diagram approach, so that it will be complementary to the resistivity drop and the Meissner effect; it enhances the sample preparation techniques with greatly increasing the amount of available samples for testing; and it deepens the abilities of microanalysis (electron backscattering diffraction) and materials surface morphology (non-invasive optical mapping profiler). The latter can also be used for parallel research and educational tasks in superconducting electronics (the ONR funded proposal "Theoretical and experimental exploration of quantum effects in superconducting electronics", N0014-16-1-2269), thus enhancing our readiness to serve the ever-growing Navy needs.
