Book Description
The discovery of novel materials brings diverse scientific opportunities by introducing novel physical phenomena, opening ways to verify and formulate theories, and enabling revolutionary industrial applications. Stabilization of novel structures in complex oxide materials is in particular of strong interest, as these materials display a broad spectrum of physical and chemical properties, along with dramatic variations in the material properties upon subtle changes in their structures. The stabilization of a material is largely governed by thermodynamic variables such as temperature, pressure, and chemical potential. Hence, stabilizing a novel, unconventional material usually requires that one or more of these thermodynamic variables are maintained at values far from the standard conditions. Epitaxial thin film growth, in which the target material is artificially exposed to large effective pressure due to the forced geometrical match with an underlying substrate with different unit cell dimensions, is a well-established example that satisfies this criterion. Another relevant example is ion intercalation, where relatively small ions such as lithium are inserted into a material (usually a two-dimensional van der Waals material) by electrochemically tuning the chemical potential of the ions, thereby changing the material's physical and chemical properties. In this work, I will show that controlled ionic modification via deintercalation can be an effective approach to stabilize novel complex oxides and demonstrate this in two material systems. First, I will discuss the meta-stable formation of IrO$_{x}$ via deintercalation of strontium in SrIrO$_{3}$, which demonstrates high oxygen evolution reaction (OER) activity and good chemical stability in acid. This motivates design strategies for high-activity OER catalysts such as the stabilization of a novel columbite polymorph of IrO$_{2}$, which I demonstrate can be achieved via epitaxial thin film growth. Second, I will show that oxygen deintercalation of perovskite nickelate stabilizes infinite-layer \textit{Ln}NiO$_{2}$ (\textit{Ln} = lanthanide), which upon hole-doping hosts unconventional superconductivity and shows striking similarities in the superconducting phase diagram to that of the cuprates despite marked differences in the two systems. Overall, this work highlights deintercalation as a powerful technique to stabilize novel complex oxides that is widely applicable to various material systems. As this approach has been rather underutilized relative to other conventional methods, there is great potential to further discover novel materials using this technique.

Book Description
Transition metal oxides are a particularly interesting class of materials because they exhibit tunable properties due to the coupling of the lattice, spin, orbital, and charge degrees of freedom. In this thesis, I explore the potential to tune their properties through growth in the [111] direction. The enhancement of functionality of materials grown in the (111)-orientation could expand the current toolbox used to design novel computing devices. The growth of LaNiO3 thin films on (111)-oriented LaAlO3 results in a unique strain state in the first few unit cells at the substrate/film interface. This strain, consisting of an expansion of the out-of-plane lattice parameter in the first few interfacial unit cells, results in insulating behavior at the substrate/film interface, the emergence of the anomalous Hall effect, and changes in the chemical valence. Notably, these changes are distinct from those observed in ultrathin (001)-oriented LaNiO3 films. This makes it clear that the strain introduced by the substrate in (111)-oriented films has the potential to greatly alter the properties of the first few unit cells of film grown on it. These thin films are also indirectly observed to be antiferromagnetically ordered. While antiferromagnetism can be difficult to directly measure, I provide evidence that these films are entirely magnetically ordered and that there is no net ferromagnetic moment. These results suggest growth in the [111] direction alters the magnetic structure of LaNiO3. Next, I explore the enhanced interfacial ferromagnetism enabled in (111)-oriented CaMnO3/CaRuO3 superlattices. These superlattices have a larger total moment and a thicker interfacial ferromagnetic phase present in the CaMnO3 as compared to (001) superlattices as well as the emergence of ferromagnetism in CaRuO3 layers. Further, an enhancement of the Curie temperature shows that growth direction can change this important engineering specification: the temperature at which magnetic ordering occurs. These changes are likely due to the differences in the orbital overlap across the (111) interface and suggest that magnetic structure can be tuned by growth direction--particularly for G-type antiferromagnets. In sum, the superlattices support the conclusion that growth of complex oxides in the (111) orientation results in an enhancement of the functionalities observed in (001)-oriented films.

Book Description
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.

Book Description
Oxide materials have been used in mainstream semiconductor technology for several decades and have served as important components, such as gate insulators or capacitors, in integrated circuits. However, in recent decades, this material class has emerged in its own right as a potential contender for alternative technologies, generally designated as ‘beyond Moore’. The 2004 discovery by Ohtomo and Hwang was a global trendsetter in this context. It involved observing a two-dimensional, high-mobility electron gas at the heterointerface between two insulating oxides, LaAlO3 and SrTiO3, supported by the rise of nascent deposition and growth-monitoring techniques, which was an important direction in materials science research. The quest to understand the origin of this unparalleled physical property and to find other emergent properties has been an active field of research in condensed matter that has united researchers with expertise in diverse fields such as thin-film growth, defect control, advanced microscopy, semiconductor technology, computation, magnetism and electricity, spintronics, nanoscience, and nanotechnology.
