Precision Synthesis and Strain Engineering of Oxide Quantum Heterostructures
Abstract
Complex oxides possess fascinating properties, including magnetism, superconductivity, ferroelectricity, multiferroicity, ionic conductivity, and more. This wide breadth of remarkable properties is the consequence of strong coupling between charge, spin, orbital, and lattice degrees of freedom. Spurred by recent advances in the synthesis of such artificial materials at the atomic scale, the physics of oxide thin films and heterostructures containing atomically smooth layers of such correlated electron materials with abrupt interfaces is a rapidly growing area. Furthermore, there are growing scientific interests and technological needs to enable heterogeneous integration of multicomponent, multifunctional systems on a small footprint to realize More Moore and More than Moore technologies. Developing thin film crystals and membranes is therefore critical to advance such technologies. In this seminar, I will review the current state-of-the-art precision and scalable synthesis techniques for functional complex oxides for the next generation of microelectronics and quantum devices.
Biography
Ho-Nyung Lee is a Corporate Fellow in the Materials Science and Technology Division at Oak Ridge National Laboratory (ORNL). He served as Program Director for the DOE-BES Materials Sciences and Engineering Program and leader for the Quantum Heterostructures group at ORNL. He joined ORNL in 2002, following his postdoctoral appointment at the Max Planck Institute of Microstructure Physics, in Germany. He got his PhD in Physics from Korea University in Seoul, Korea. His research interests involve the epitaxial synthesis of oxide-based quantum and energy materials by pulsed laser epitaxy and the physics of correlated oxide heterostructures. Dr. Lee is one of the 2006 PECASE Award winners from the White House and is a fellow of the American Association for the Advancement of Science (AAAS), American Physical Society (APS), Materials Research Society (MRS), and Korean Academy of Science and Technology.
