This book was released on 2020 with total page 127 pages. Available in PDF, EPUB and Kindle. Book excerpt: Emergent behaviors arising from strongly correlated electron materials continue to puzzle physicists as there are still no clear explanations behind the underpinning mechanisms. The key hides in the collective behavior originating from the interactions among the electronic degrees of freedom, and the objective is to use various experimental probes to investigate the spin, charge, orbital and lattice contributions and their correlated behavior. This dissertation presents a study into how several advanced coherent x-ray techniques can be used to investigate the nanoscale landscape, both spatially and temporally, of strongly correlated electron materials to understand both the underlying physics and how to incorporate these materials into technological devices. In particular, resonant elastic x-ray scattering and x-ray photon correlation spectroscopy are used to study the charge and orbital order tied to the metal-insulator transition in magnetite (Fe3O4), first observed by Verwey back in 1939. The results presented in Chapter 3 suggest that trimeron fluctuations due to thermal electron hopping among Fe 3d orbital sites play a vital role in the metal-insulator transition. Chapter 4 is an investigation into electron-phonon coupling times in elemental chromium using ultrafast x-ray pump-probe. Chapters 5 and 6 focus on the use of x-ray nanodiffraction to spatially resolve the strain in square LSMO nanoislands and the electrical-induced strain propagation in a ferroelectric/ferromagnetic (PZT/LSMO) heterostructure. Understanding the spatial extent of the correlation between strain to both the electric polarization and magnetic domains in these materials is essential for designs in sensory and computing architectures. Finally, Chapter 7 presents a simulation of a double probe x-ray speckle visibility spectroscopy experiment, a technique that relies on the change of contrast on an area detector to resolve dynamic timescales in the femto- to nanosecond range. Based on the simulated results, an analysis method that relies on selective binning of the detector image pixels is proposed to overcome the obstacles presented by an experimental imperfections such as an angular misalignment between the two probes.

Download or read book Coherent X ray Studies of Nanoscale Defects and Domains in Functional Materials written by Boyan Krassimirov Stoychev and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Functional materials with tunable chemical, electronic, and magnetic properties play a pivotal role in advancing modern technology and addressing critical global challenges. A detailed understanding of the structure-property relations in these materials can unlock breakthroughs in their development. Nanoscale structures can have profound effects onthe functionality of a material. This dissertation presents how advanced coherent X-ray techniques can be used to probe these nanoscale structures. In particular, Bragg coherent diffractive imaging is used to map lattice strain and defects, while resonant elastic X-ray scattering can probe nanoscale magnetic domains. The results in Chapter 3 demonstrate the superior electrochemical homogeneity of cathode material fabricated using a novel dry approach, compared to the conventional slurry method, helping to explain observed performance improvements. We further observe a gradient in the electrochemical performance of the cathode as a function of distance from the battery separator. Chapter 4 is an investigation of the strain and defects found in a novel Na-Y-Zr-Cl solid-state electrolyte, as well as the co-existence of two competing crystalline phases. Finally, Chapter 5 presents the discovery of an anomalous order in Fe electrons in magnetite (Fe3O4) thin films with a strong magnetic signature. Based on the modeling of the observed reciprocal space structure, this order is likely to be ultra-thin spin domains with a thickness of 0.5 unit cells.

Download or read book Physics of and Science with X Ray Free Electron Lasers written by J. Hastings and published by IOS Press. This book was released on 2020-12-18 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many X-Ray Free-Electron Lasers (X-FELs) have been designed, built and commissioned since the first lasing of the Linac Coherent Light Source in the hard and soft X-ray regions, and great progress has been made in improving their performance and extending their capabilities. Meanwhile, experimental techniques to exploit the unique properties of X-FELs to explore atomic and molecular systems of interest to physics, chemistry, biology and the material sciences have also been developed. As a result, our knowledge of atomic and molecular science has been greatly extended. Nevertheless, there is still much to be accomplished, and the potential for discovery with X-FELs is still largely unexplored. The next generation of scientists will need to be well versed in both particle beams/FEL physics and X-ray photon science. This book presents material from the Enrico Fermi summer school: Physics of and Science with X-Ray Free-Electron Lasers, held at the Enrico Fermi International School of Physics in Varenna, Italy, from 26 June - 1 July 2017. The lectures presented at the school were aimed at introducing graduate students and young scientists to this fast growing and exciting scientific area, and subjects covered include basic accelerator and FEL physics, as well as an introduction to the main research topics in X-FEL-based biology, atomic molecular optical science, material sciences, high-energy density physics and chemistry. Bridging the gap between accelerator/FEL physicists and scientists from other disciplines, the book will be of interest to all those working in the field.
