Book Description
The manipulation of the spin of charge carriers within solid-state materials has the potential to greatly reduce power consumption and increase computational speeds and information storage densities. The development of these spintronic devices requires development of new materials which can be used to efficiently generate, propagate, and detect spin currents. One promising class of materials to use are the complex oxide perovskites, which exhibit a rich variety of tunable electronic and magnetic properties and which can be interfaced and combined to create emergent interfacial phenomena. In this thesis, I will cover two efforts to develop materials for spintronics applications. The first part of this thesis focuses on the surprising discovery that the pulsed laser deposition process used to grow homoepitaxial thin films of oxygen-deficient SrTiO(3-x) can significantly change the properties of the underlying SrTiO3 substrate. In the search for a low-dimensional metal with high mobility and high spin-orbit coupling, I find that the plume dynamics and kinetics during thin film growth cause significant oxygen-reduction of and conductivity in the entire substrate, significantly faster than by other processes. This has significant implications for thin film growth of many different materials. In the second part of the thesis, I will focus on spin current generation via microwaves in a low-loss ferromagnetic metal, (La2/3Sr1/3)MnO3, and the transmission of spin angular momentum across an epitaxial interface with a non-magnetic, high spin-orbit coupled metal, CaRuO3. Using ferromagnetic resonance spectroscopy to both generate these spin currents as well as measure magnetic properties, I not only find evidence of efficient spin pumping across the interface, but also find that the orthorhombic CaRuO3 can affect the magnetic and electronic anisotropy in these heterostructures, likely due to structural effects. While complex oxides remain promising candidates for spintronics, the integration of different materials offers additional degrees of freedom which must be fully understood to engineer additional functionality.

Book Description
This handbook provides a comprehensive review of the entire field of laser micro and nano processing, including not only a detailed introduction to individual laser processing techniques but also the fundamentals of laser-matter interaction and lasers, optics, equipment, diagnostics, as well as monitoring and measurement techniques for laser processing. Consisting of 11 sections, each composed of 4 to 6 chapters written by leading experts in the relevant field. Each main part of the handbook is supervised by its own part editor(s) so that high-quality content as well as completeness are assured. The book provides essential scientific and technical information to researchers and engineers already working in the field as well as students and young scientists planning to work in the area in the future. Lasers found application in materials processing practically since their invention in 1960, and are currently used widely in manufacturing. The main driving force behind this fact is that the lasers can provide unique solutions in material processing with high quality, high efficiency, high flexibility, high resolution, versatility and low environmental load. Macro-processing based on thermal process using infrared lasers such as CO2 lasers has been the mainstream in the early stages, while research and development of micro- and nano-processing are becoming increasingly more active as short wavelength and/or short pulse width lasers have been developed. In particular, recent advances in ultrafast lasers have opened up a new avenue to laser material processing due to the capabilities of ultrahigh precision micro- and nanofabrication of diverse materials. This handbook is the first book covering the basics, the state-of-the-art and important applications of the dynamic and rapidly expanding discipline of laser micro- and nanoengineering. This comprehensive source makes readers familiar with a broad spectrum of approaches to solve all relevant problems in science and technology. This handbook is the ultimate desk reference for all people working in the field.

Book Description
Photoemission is one of the principal techniques for the characterization and investigation of condensed matter systems. The field has experienced many developments in recent years, which may also be put down to important achievements in closely related areas. This timely and up-to-date handbook is written by experts in the field who provide the background needed by both experimentalists and theorists. It represents an interesting framework for showing the connection between theory and experiment by bringing together different concepts in the investigation of the properties of materials. The work addresses the geometric and electronic structure of solid surfaces and interfaces, theoretical methods for direct computation of spectra, experimental techniques for data acquisition, and physical models for direct data interpretation. It also includes such recent developments as full hemisphere acceptance in photoemission, two-electron photoemission, (e, 2e) electron diffraction, and photoelectron-electron/hole interaction.

Book Description
For 50 years conventional electronics has ignored the electron spin. The manipulation and utilisation of the electron spin heralds an exciting and rapidly changing era in electronics, combining the disciplines of magnetism and traditional electronics. The first generation of "spintronic" devices (such as read heads based on giant magnetoresistance or non-volatile magnetic random access memories) have already gained dominant positions in the market place. This volume, the first of its kind on spin electronics describes all the essential topics for new researchers entering the field. It covers magnetism and semiconductor basics, micromagnetism, experimental techniques, materials science, device fabrication and new developments in spin-dependent processes. At the end of most chapters are a number of exercises and worked problems to aid the reader in understanding this fascinating new field.

Book Description
Pulsed ultraviolet light from a XeF excimer laser was used to grow thin films of zinc oxide and tin dioxide on (111) p-type silicon wafers within a versatile high vacuum laser deposition system. This pulsed laser deposition system was self-designed and self-built. Parameters such as pressure, target temperature, and distance from the target to the substrate can be adjusted in the system. Scanning electron microscopy, energy dispersive X-ray spectroscopy, X-ray diffraction spectroscopy, Raman spectroscopy and ellipsometry were used to analyze the structures and properties of ZnO and SnO2 thin films. The critical temperature required to fabricate a crystalline ZnO thin film by pulsed laser deposition was found and has been confirmed. For the SnO2 thin film, the critical temperature required to generate a crystalline structure could not be found because of the temperature limit of the substrate heater used in the experiment. In SnO2 thin films, thermal annealing has been used to convert into crystalline structure with (110), (101) and (211) orientations. After fabricating the amorphous SnO2 thin films, they were put into an oven with specific temperatures to anneal them. The minimum annealing temperature range was found for converting the amorphous SnO2 thin films into SnO2 thin films with a crystalline structure. Thermal annealing has also been applied to some amorphous ZnO thin films which were fabricated under the critical temperature required to produce crystalline ZnO thin films. The minimum annealing temperature range for amorphous ZnO thin films was found and only one orientation (002) shown after annealing. Laser annealing technology has also been applied for converting both amorphous ZnO and SnO2 thin films, and results show that this method was not well suited for this attempt. ZnO thin films and SnO2 thin films with a crystalline structure have inportant widely used in industry, for example, application in devices such as solar cells and UV or blue-light-emitting devices. The aim of this research is to help improving the manufacturing process of ZnO and SnO2 thin films.
