Surfaces and interfaces where different materials contact each other are the sites of chemical reactions and also exhibit peculiar behavior due to interactions between the materials and symmetry breaking. Therefore, such peculiarities are attracting attention from the academic viewpoint to understand how the interface exhibits unique behavior, and the mechanism is attracting attention to improve the performance of various industrial devices that utilize surfaces and interfaces. However, the combinations of chemical species that constitute interfaces are diverse, as are the physical quantities associated with their functions. To discern relationships among these elements, it is necessary to distinguish the relationships between functions and quantities observed through experimentation. However, the number of combinations is enormous and multifaceted, making it difficult to accomplish this feat with a single method.
Based on this background, this theme proposes combining existing advanced methods rather than taking a vertical thinking approach to further advancing existing methods. This method involves performing multi-probe measurements to evaluate the target interface, especially soft interfaces composed of organic materials, using advanced measurements with quantum beams. This approach yields multifaceted data that includes information directly related to functional expression, such as structure, composition, and chemical state. Since it is difficult to obtain consistent results from each experimental method, we will develop a method to select "true solutions" by combining various macroscopic measurements and build a platform to share information on analytical methods according to these combinations.
