This book was released on 2017-09-18 with total page 133 pages. Available in PDF, EPUB and Kindle. Book excerpt: This impressive thesis offers a comprehensive scientific study of the alkaline earth niobates and describes their nonlinear optical properties for the first time. It explores the crystal structure, electrical properties, optical absorption properties, hot carrier dynamics, nonlinear optical property and strain-induced metal to insulator transition of alkaline earth niobates using advanced experimental techniques. These alkaline earth niobates can have a strong plasmon resonance in the visible range due to their large carrier density, and this unique property gives rise to the emergent phenomenon of photocatalysis and nonlinear optical properties. This series of intrinsic plasmonic materials based on niobates, can be used as a photocatalyst to split water under sunlight, a novel saturable absorber in the high-power ultrashort pulsed laser system, and as a sensor in microelectromechanical systems.

This book was released on 1994 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: Epitaxial PbTiO3 films were prepared by metal-organic chemical vapor deposition (MOCVD) on MgO(001), SrTiO3(001) and LaAlO3(001) surfaces. Four-circle X-ray diffraction and optical waveguiding experiments were performed to characterize the deposited films. The films on all three substrates were single-crystal; however, the domain structure of the films was strongly dependent on the substrate material. Films on MgO and LaAIO3 substrates showed a large amount of 90° domain structures, whereas, the degree of twinning was greatly suppressed for films on SrTiO3. The refractive indices and optical birefringence of the films were measured as a function of wavelength using the film-prism coupling method. The authors found that for films on LaAIO3(001), the ordinary index and for films on MgO(001) both the ordinary and extraordinary refractive indices were higher than those of bulk single-crystal PbTiO3. For films grown on SrTiO3(001), the ordinary refractive index was very close to that of single crystal PbTiO3. They correlate the increased refractive index and the reduced birefringence to the degree of epitaxial strain and twinning in the samples, respectively.

Book Synopsis Structure and Transport Properties of Epitaxial Oxide Thin Films by : Junsoo Shin
Download or read book Structure and Transport Properties of Epitaxial Oxide Thin Films written by Junsoo Shin and published by . This book was released on 2007 with total page 207 pages. Available in PDF, EPUB and Kindle. Book excerpt: Epitaxial thin films and heterostructures based on perovskite oxides have attracted significant attention in physics since perovskites exhibit an enormous range of electrical, magnetic, and optical properties, making them exciting systems for studies of the fundamental physical mechanisms of interactions between electron, lattice, and spin degrees of freedom. This dissertation has been focused on ferroelectricity in low-dimensional ferroelectric materials using ultra-thin ferroelectric epitaxial films (BaTiO3) with a metallic electrode (SrRuO3) by studying polarized ordering of the crystal structure and electronic transport through the films. High quality and highly oxidized epitaxial films are a prerequisite for the clear observation of physical properties such as ferroelectricity which depends on a sensitive balance of lattice structure, dynamics, and charge distribution. Measurements in low dimensional, ultra-thin films require a controlled surface status through in-situ characterization. As is demonstrated here, fundamental physical phenomena on surfaces and in ultra-thin films are easily modified due to reactivity in ambient air, even for oxide materials generally considered inert. This study is centered on in-situ low energy electron diffraction and scanning tunneling spectroscopy of BaTiO3 films grown on SrRuO3 electrodes on a SrTiO3 substrate. Results show out-of-plane polarized structure and polarization switching, which provide evidence of ferroelectricity in films down to 4 ML. Surface reconstruction in 1-2 ML thick BaTiO3 films is seriously affected by the interface between BaTiO3 films and SrRuO3 bottom electrode. Our observation in epitaxial BaTiO3 films indicates the existence of ferroelectricity with a lower limit (4 ML) for the minimum thickness than theoretical expectation (6 ML), which results from the difference of film stress, termination on films, and depolarizing screening.

Book Synopsis Preparation and Optical Properties of Epitaxial Thin Films of Some Ii-vi Semiconducting Compounds by : Rudolf Ludeke
Download or read book Preparation and Optical Properties of Epitaxial Thin Films of Some Ii-vi Semiconducting Compounds written by Rudolf Ludeke and published by . This book was released on 1968 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: The work describes mainly the preparation and optical properties of epitaxial thin films of some II-IV semiconducting compounds. In addition optical modulation experiments on both thin film and bulk samples are reported. Epitaxial thin films of CdTe, HgTe, the alloy system CdxHg1-xTe, and CdSe were prepared by a flash evaporation technique on BaF2 substrates. The effects of various deposition parameters on the electron diffraction and optical structures of CdTe and CdSe were analyzed in detail. Optical transmission measurements on the epitaxial thin films were made at room and liquid nitrogen temperatures in the spectral region from 2 to 6 eV. Two novel approaches of optical modulation methods were pursued: piezo-transmission on Ge and CdTe polycrystalline films and electroreflectivity on bulk CdTe using an integral sandwich technique. Both methods were used down to liquid helium temperatures.

Book Synopsis Advanced Materials for Integrated Optical Waveguides by : Xingcun Colin Tong Ph.D
Download or read book Advanced Materials for Integrated Optical Waveguides written by Xingcun Colin Tong Ph.D and published by Springer Science & Business Media. This book was released on 2013-10-17 with total page 574 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive introduction to integrated optical waveguides for information technology and data communications. Integrated coverage ranges from advanced materials, fabrication, and characterization techniques to guidelines for design and simulation. A concluding chapter offers perspectives on likely future trends and challenges. The dramatic scaling down of feature sizes has driven exponential improvements in semiconductor productivity and performance in the past several decades. However, with the potential of gigascale integration, size reduction is approaching a physical limitation due to the negative impact on resistance and inductance of metal interconnects with current copper-trace based technology. Integrated optics provides a potentially lower-cost, higher performance alternative to electronics in optical communication systems. Optical interconnects, in which light can be generated, guided, modulated, amplified, and detected, can provide greater bandwidth, lower power consumption, decreased interconnect delays, resistance to electromagnetic interference, and reduced crosstalk when integrated into standard electronic circuits. Integrated waveguide optics represents a truly multidisciplinary field of science and engineering, with continued growth requiring new developments in modeling, further advances in materials science, and innovations in integration platforms. In addition, the processing and fabrication of these new devices must be optimized in conjunction with the development of accurate and precise characterization and testing methods. Students and professionals in materials science and engineering will find Advanced Materials for Integrated Optical Waveguides to be an invaluable reference for meeting these research and development goals.
