We work on the epitaxial deposition of functional oxide thin films. We use in-situ diagnostic tools during the pulsed laser depostion process to advance the design of technologically relevant oxide thin films. In particual the combination of state of the art non-linear optics monitoring and electron spectroscopy in situ allows to investigate the dynamics of the functional properties as we grow the films form the very first unit cell. We improve the understanding of the evolution of physical properties of epitaxial thin films in the ultrathin regime and investige interface related phenomena in multilayers.
SCIENTIFIC ACTIVITIES
Head of the Nonlinear optics for Epitaxial growth of Advanced Thin films laboratory (NEAT lab)
Currently running the Nonlinear optics for Epitaxial growth of Advanced Thin films (NEAT) laboratory within the institute of Multifunctional Ferroic Materials in the Materials Department, Prof. Trassin is leading a research team focusing on oxide interfaces and epitaxial ferroelectric and multiferroic thin films. His research involves the thin multifunctional film growth by pulsed laser deposition and the advanced characterization of their domain structures. Prof. Trassin is pioneering the investigation of thin films functionalities in-situ, during the epitaxial synthesis, using an unprecedented combination of experimental techniques.
