Interplay between Interface and Functionality in Epitaxial Nanocomposite Films

Tunable functionalities and emergent behaviors have been accomplished by interfacing different materials to form nanocomposites. Epitaxial nanocomposite film, in particular, has been considered as a very versatile platform to tune, probe, and exploit novel physical properties that cannot be obtained in the individual constituents. In this talk, I will overview our research activities in rational design and control of functionalities of epitaxial nanocomposite oxide films. Using controlled synthesis, advanced characterization, and theoretical modeling, we are able to provide a framework to understand the interplay between the interface and the functionality in epitaxial nanocomposite films. I will use nanoparticles in a matrix, superlattices, and vertically aligned epitaxial nanocomposites as model systems to show our approaches to design, control, and tune the transport properties of a range of complex metal oxide films such as ferroelectric, ferromagnetic, and superconducting materials.

Quanxi Jia is an Empire Innovation Professor and National Grid Professor of Materials Research at the University at Buffalo (UB) - the State University of New York. Prior to joining UB in 2016, he had worked at Los Alamos National Laboratory for 24 years, with the last two years serving as the co-Director and then Director of the Center for Integrated Nanotechnologies, a US Department of Energy Nanoscale Science Research Center operated jointly by Los Alamos and Sandia National Laboratories. His research has focused on nanostructured and multifunctional materials, with a particular effort on the synthesis and study of processing-structure–property relationships of epitaxial films for energy and electronic applications. He has authored/co-authored over 500 peer-reviewed journal articles and holds 49 U.S. patents. He is an elected Fellow of the Los Alamos National Laboratory, the Materials Research Society, the American Physical Society, the American Ceramic Society, the American Association for the Advancement of Science, the Institute of Electrical and Electronics Engineers, and the National Academy of Inventors.
