This leads to new results in the fields of superconductivity, electronic polarization states and nanoscale phenomena. Among these, the observation of anomalous polar moments is of great relevance for understanding the electric-field-induced metal-to-insulator transistion; and the demonstration that confocal Raman spectroscopy of backfolded acoustic photons in metal-oxide multilayers can be used as a powerful characterization tool for monitoring their interface properties and layer thickness is an important technical development for the engineering of such functional oxide heterostructures.Springer Theses, Recognizing Outstanding Ph.D. Research,2190-5061Optical spectroscopySuperconductivitySuperconductorsSurfaces (Technology)Thin filmsElectronicsMaterialsOptical SpectroscopySuperconductivitySurfaces, Interfaces and Thin FilmElectronic MaterialsOptical spectroscopy.Superconductivity.Superconductors.Surfaces (Technology)Thin films.ElectronicsMaterials.Optical Spectroscopy.Superconductivity.Surfaces, Interfaces and Thin Film.Electronic Materials.929.374541.2242Lyzwa Fryderyk1261727MiAaPQMiAaPQMiAaPQ9910616202003321Phononic and Electronic Excitations in Complex Oxides Studied with Advanced Infrared and Raman Spectroscopy Techniques2940550UNINA
