Ionic transport in nanostructures at high eld strength has recently gained attention, because novel types of computer memory with potentially superior properties rely on such phenomena. The applied voltages are only moderate, but they drop over the distance of a few nanometers and lead to extreme eld strengths in the MV/cm region. Such strong elds contributes signi cantly to the activation energy for ionic jump processes. This leads to an exponential increase of transport speed with voltage. Conventional high-temperature ionic conduction, in contrast, only relies on thermal activation for such jumps. In this thesis, the transport of minute amounts of oxygen through a thin dielectric layer sandwiched between two thin conducting oxide electrodes was detected semiquantitatively by measuring the conductance change of the electrodes after applying a current through the dielectric layer. The relative conductance change G=G as a function of current I and duration t follows over several orders of magnitude a simple, empirical law of the form G=G = CIAtB with t parameters C, A and B; A;B 2 [0; 1]. This empirical law can be linked to a predicted exponential increase of the transport speed with voltage at high eld strength. The behavior in the time domain can be explained with a spectrum of relaxation processes, similar to the relaxation of dielectrics. The in uence of temperature on the transport is strong, but still much lower than expected. This contradicts a commonly used law for high- eld ionic transport. The di erent oxide layers are epitaxial with thicknesses between 5 and 70 nm. First large-scale test samples were fabricated using shadow masks. The general behavior of such devices was studied extensively. In an attempt to achieve quantitative results with defect-free, miniaturized devices, a lithographic manufacturing process that uses repeated steps of epitaxial deposition and structuring of the layers was developed. It employs newly developed and optimized wet chemical etching processes for the conducting electrodes. First high-quality devices could be manufactured with this process and con rmed that such devices su er less from parasitic e ects. The lithographically structured samples were made from di erent materials. The results from the rst test samples and the lithographically structured samples are therefore not directly comparable. They do exhibit however in principle the same behavior. Further investigation of such lithographically structured samples appears promising

Perovskite solar cells (PSCs) have attracted increasing interest from researchers due to their superb power conversion efficiencies. The intrinsic trap defects, unavoidably formed in the fabrication process, can induce nonradiative recombination, ion migration, I-V hysteresis, and instability of PSCs. However, trap defects are not always harmful. Fully understanding the fundamentals of trap defects as well as the passivation and doping strategies is helpful for further improving device efficiency and stability. This book summarizes the methods and strategies of defect passivation and material doping aiming to clearly describe the underlying mechanisms for high-efficiency and stable PSCs. • Introduces the fundamental characteristics of perovskite material defects • Discusses the main strategies, principles, and applications of defect passivation • Describes defect passivation consequences and characterization methods • Covers principles, methods, and applications of doping engineering in perovskites • Explores the structural design, advantages, characteristics, fabrication methods, and future development of perovskite homojunction Engineers and researchers working with photovoltaic generation, solar cells, semiconductors, and related topics will find this book to be an invaluable resource.

This book summarizes the most recent and compelling experimental results for complex oxide interfaces. The results of this book were obtained with the cutting-edge photoemission technique at highest energy resolution. Due to their fascinating properties for new-generation electronic devices and the challenge of investigating buried regions, the book chiefly focuses on complex oxide interfaces. The crucial feature of exploring buried interfaces is the use of soft X-ray angle-resolved photoemission spectroscopy (ARPES) operating on the energy range of a few hundred eV to increase the photoelectron mean free path, enabling the photons to penetrate through the top layers – in contrast to conventional ultraviolet (UV)-ARPES techniques. The results presented here, achieved by different research groups around the world, are summarized in a clearly structured way and discussed in comparison with other photoemission spectroscopy techniques and other oxide materials. They are complemented and supported by the most recent theoretical calculations as well as results of complementary experimental techniques including electron transport and inelastic resonant X-ray scattering.
