Derek Meyers, University of California, Title: Forging next generation materials through atomic layer engineering
Abstract: Society?s progress throughout history has been driven by our ability to craft the world around us into functional technologies. In this talk, we will explore one of the most recent emergent methods to create artificial crystalline structures of complex oxides with unprecedented properties and functionalities. Pulsed laser deposition allows stacking of single atomic layers of disparate materials with sharp interfaces and high crystalline quality. To directly probe these nanoscale interfaces, advanced synchrotron X-ray characterization will be introduced as a powerful method for investigating the charge and magnetic behavior of these artificial structures. Fascinating physical phenomena derived from the strongly correlated electrons, such as superconductivity and 2D magnetism, will be showcased as recent paragons of this growth and characterization methodology. In particular, the role of electron-phonon coupling in the recent SrTiO3-based superconductors and the magnetic behavior of isolated strongly spin-orbit coupled SrIrO3 layers will be discussed. We will conclude this talk with a discussion on the promising future applications for these methods, with an emphasis on topological phenomena and quantum information science.
