The Materials Physics of Complex Oxides


Charles Ahn
Yale University, Department of Applied Physics

Complex oxide materials exhibit a tremendous diversity of behavior encompassing a range of functional properties, such as magnetism, ferroelectricity, multiferroicity, and superconductivity.  As diverse as this behavior is, an even richer spectrum of possibilities becomes available if one starts to combine different complex oxides together with atomic-scale precision to create new artificially structured, heterogeneous systems.  In these nanostructured materials, cross-coupling between the functionalities of the individual component materials allows one material to modify the properties of the other constituent.  In this talk, we describe the electrostatic control of strongly correlated behavior, such as magnetism and superconductivity, using intense electric fields, and we discuss applications of this approach to address current challenges in the modern electronics industry.
