Ferroelektrische Eigenschaften von Kondensatoren mit epitaktischen BaTiO3-Dünnschichten
Abstract Epitaxial BaTiO3 films are interesting for the integration into microelectronics due to the ferroelectric properties and high permittivity. In this work epitaxial BaTiO3 thin-films were grown on conductive layers, SrRuO3 und La2/3Ca1/3MnO3, by pulsed laser deposition. The growth on …

Microstructure evolution and crystallisation kinetics of pure and isovalently substituted lead titanate thin films derived by chemical solution deposition
Electroceramic thin films are an essential component in modern technologies of many kinds. In this regard, perovskite materials based on lead titanate (PbTiO3) are especially relevant as functional layers in piezoelectric, ferroelectric, pyroelectric, and other devices. The industrially most …

All-electron GW calculations for perovskite transition metal oxides
Ever since the middle of the 1920s, when compounds from the perovskite structure family played a key role in the groundbreaking work of Goldschmidt on material synthesis, perovskite transition-metal oxides (TMOs) have repeatedly stimulated new activities in fundamental research as well as in the …

Scattering Scanning Near-Field Optical Microscopy on Anisotropic Dielectrics
Near-field optical microscopy allows the nondestructive examination of surfaces with a spatial resolution far below the diffraction limit of Abbe. In fact, the resolution of this kind of microscope is not at all dependent on the wavelength, but is typically in the range of 10 to 100 nanometers. On …
