This book was released on 2016 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: The creation of attosecond pulses using high harmonic generation (HHG) to produce extreme ultraviolet light (XUV) pulses has enabled table-top core-level spectroscopy in both the gas and solid phase. Because HHG relies on a near infrared (NIR) driver pulse to create the XUV radiation, it is readily incorporated into pump-probe transient absorption and photoelectron spectroscopy experiments, giving way to measurements with unprecedented temporal resolution. The ability of attosecond XUV pump-probe spectroscopy to study solid state semiconductor materials allows for the interrogation of carriers on the timescales where a separation between electronic and lattice dynamics can occur. This will have far reaching implications addressing the fundamental carrier physics that govern the next generation of hot carrier charge transfer devices, which are at the forefront of photocatalytic and electronic device development. In this dissertation, a literature review of XUV transient absorption on solids using HHG is presented in Chapter 1. This chapter details the progress from femtosecond experiments on metal-oxide thin films to attosecond time-resolved experiments on semiconductors. In Chapter 2, the design and construction of the attosecond transient absorption apparatus capable of studying ultrafast dynamics in both solid state and gas phase samples using a near infrared (NIR) pump and an extreme ultraviolet (XUV) probe is presented. Chapter 3 presents transient absorption experiments done on germanium thin films, which measure both electrons and hole dynamics simultaneously in a single measurement. These results are supported by work from a theory collaboration. in Chapter 4, preliminary work on silicon germanium alloys is presented. While the results need further confirmation by additional experiments and characterization, it is clear that signals from hot carrier relaxation are present. Chapter 5 presents a theoretical investigation of a future experiment on silver nanoparticles using a velocity map imaging (VMI) device. The key feature of this theoretical study is the identification of a metric to follow the near-field of the plasmon, isolated from the electric field of the exciting laser pulse.

Book Synopsis Strong-field and Attosecond Physics in Solids by :

Book excerpt: We review the status of strong-field and attosecond processes in bulk transparent solids near the Keldysh tunneling limit. For high enough fields and low-frequency excitations, the optical and electronic properties of dielectrics can be transiently and reversibly modified within the applied pulse. In Ghimire et al (2011 Phys. Rev. Lett. 107 167407) non-parabolic band effects were seen in photon-assisted tunneling experiments in ZnO crystals in a strong mid-infrared field. Using the same ZnO crystals, Ghimire et al (2011 Nat. Phys. 7 138-41) reported the first observation of non-pertubative high harmonics, extending well above the bandgap into the vacuum ultraviolet. Recent experiments by Schubert et al (2014 Nat. Photonics 8 119-23) showed a carrier envelope phase dependence in the harmonic spectrum in strong-field 30 THz driven GaSe crystals which is the most direct evidence yet of the role of sub-cycle electron dynamics in solid-state harmonic generation. The harmonic generation mechanism is different from the gas phase owing to the high density and periodicity of the crystal. For example, this results in a linear dependence of the high-energy cutoff with the applied field in contrast to the quadratic dependence in the gas phase. Sub-100 attosecond pulses could become possible if the harmonic spectrum can be extended into the extreme ultraviolet (XUV). Here we report harmonics generated in bulk MgO crystals, extending to $\sim 26$ eV when driven by ~35 fs, 800 nm pulses focused to a ~1 VÅ$^{-1}$ peak field. The fundamental strong-field and attosecond response also leads to Wannier-Stark localization and reversible semimetallization as seen in the sub-optical cycle behavior of XUV absorption and photocurrent experiments on fused silica by Schiffrin et al (2013 Nature 493 70-4) and Schultze et al (2013 Nature 493 75-8). These studies are advancing our understanding of fundamental strong-field and attosecond physics in solids with potential applications for compact coherent short-wavelength sources and ultra-high speed optoelectronics.

Book Synopsis Attosecond Transient Absorption of Solid-State and Phase-Change Materials by : Marieke Faye Jager
Download or read book Attosecond Transient Absorption of Solid-State and Phase-Change Materials written by Marieke Faye Jager and published by . This book was released on 2017 with total page 109 pages. Available in PDF, EPUB and Kindle. Book excerpt: Attosecond science, utilizing short bursts of extreme ultraviolet light, has opened up a fascinating new field of ultafast light-matter interactions, where dynamics in atomic, molecular, and solid state systems can now be followed on the timescale of electron motion. In this dissertation, applications of attosecond pulses toward performing transient absorption spectroscopy experiments on complex electron-correlation-driven processes in material systems are described. In the first chapter, a brief overview of ultrafast spectroscopy, attosecond pulse production, and light-matter interaction in the extreme ultraviolet is provided, which offers the necessary breadth and background for the detailed case study that follows, on the insulator-to-metal phase transition in vanadium dioxide. The origin of the bandgap in vanadium dioxide, which is not predicted to exist under conventional single-particle band theories, has been explained as the result of either electron correlation or structural distortion. The goal of the experiments presented herein is to use transient absorption spectroscopy with attosecond pulses to characterize the timescale of this process and gain a mechanistic understanding of how it occurs. Because vanadium dioxide is heat sensitive, an apparatus had to be specifically tailored to this type of experiments, and it is described in the second chapter. The results and analysis, including extreme ultraviolet static and time-resolved measurements on both the insulating and metallic phases, are described in the third chapter. The second half of this dissertation describes the design and construction of a new vacuum endstation to perform attosecond-pump attosecond-probe measurements, which was constructed and tested at Berkeley and installed at a high power attosecond beamline at the University of Central Florida. Ray tracing simulation and design considerations for the optical layout are described in the fourth chapter, and design of the vacuum endstation, diagnostics, and preliminary experiments and testing can be found in the fifth chapter.

Available in PDF, EPUB and Kindle. Book excerpt: This book documents the recent vivid developments in the research field of ultrashort intense light pulses for probing and controlling ultrafast dynamics. The recent fascinating results in studying and controlling ultrafast dynamics in ever more complicated systems such as (bio-)molecules and structures of meso- to macroscopic sizes on ever shorter time-scales are presented. The book is written by some of the most eminent experimental and theoretical experts in the field. It covers the new groundbreaking research directions that were opened by the availability of new light sources such as fully controlled intense laser fields with durations down to a single oscillation cycle, short-wavelength laser-driven attosecond pulses and intense X-ray pulses from the upcoming free electron lasers. These light sources allowed the investigation of dynamics in atoms, molecules, clusters, on surfaces and very recently also in nanostructures and solids in new regimes of parameters which, in turn, led to the identification of completely new dynamics and methods for controlling it. Example topics covered by this book include the study of ultrafast processes in large molecules using attosecond pulses, control of ultrafast electron dynamics in solids with shaped femtosecond laser pulses, light-driven ultrafast plasmonic processes on surfaces and in nanostructures as well as research on atomic and molecular systems under intense X-ray radiation. This book is equally helpful for people who would like to step into this field (e.g. young researchers), for whom it provides a broad introduction, as well as for already experienced researchers who may enjoy the exhaustive discussion that covers the research on essentially all currently studied objects and with all available ultrafast pulse sources.
