Book Synopsis Chemical Solution Deposition of Functional Oxide Thin Films by : Theodor Schneller
Download or read book Chemical Solution Deposition of Functional Oxide Thin Films written by Theodor Schneller and published by Springer Science & Business Media. This book was released on 2014-01-24 with total page 801 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first text to cover all aspects of solution processed functional oxide thin-films. Chemical Solution Deposition (CSD) comprises all solution based thin- film deposition techniques, which involve chemical reactions of precursors during the formation of the oxide films, i. e. sol-gel type routes, metallo-organic decomposition routes, hybrid routes, etc. While the development of sol-gel type processes for optical coatings on glass by silicon dioxide and titanium dioxide dates from the mid-20th century, the first CSD derived electronic oxide thin films, such as lead zirconate titanate, were prepared in the 1980’s. Since then CSD has emerged as a highly flexible and cost-effective technique for the fabrication of a very wide variety of functional oxide thin films. Application areas include, for example, integrated dielectric capacitors, ferroelectric random access memories, pyroelectric infrared detectors, piezoelectric micro-electromechanical systems, antireflective coatings, optical filters, conducting-, transparent conducting-, and superconducting layers, luminescent coatings, gas sensors, thin film solid-oxide fuel cells, and photoelectrocatalytic solar cells. In the appendix detailed “cooking recipes” for selected material systems are offered.

This book was released on 2005-11-21 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oxides form a broad subject area of research and technology development which encompasses different disciplines such as materials science, solid state chemistry, physics etc. The aim of this book is to demonstrate the interplay of these fields and to provide an introduction to the techniques and methodologies involving film growth, characterization and device processing. The literature in this field is thus fairly scattered in different research journals covering one or the other aspect of the specific activity. This situation calls for a book that will consolidate this information and thus enable a beginner as well as an expert to get an overall perspective of the field, its foundations, and its projected progress.
Book Synopsis Novel Amorphous Iron-dysprosium-terbium-oxide Thin Films by : Humaira Taz
Download or read book Novel Amorphous Iron-dysprosium-terbium-oxide Thin Films written by Humaira Taz and published by . This book was released on 2018 with total page 109 pages. Available in PDF, EPUB and Kindle. Book excerpt: Amorphous oxides which are transparent and conducting find use in display devices and as top electrodes in energy applications, while those which are conducting and magnetic have the potential to be used in spintronics. With the fast approaching limit of Moore’s law, new materials are needed where the spin and polarization of the electrons are coupled. Despite progress in transparent conductors, materials selection is limited by the need to have wide optical bandgap and conduction via s-orbital. In contrast, search for new spintronics materials has picked up only in the last decade. Here we report the synthesis, characterization, and application of a new oxide made from Fe, Tb, and Dy - elements that do not conduct via the s-orbital. Thin films (100 nm) of this oxide were synthesized by pulsed laser deposition (PLD) as a function of varying oxygen pressure, and by electron-beam evaporation as a function of the cation composition, and then annealed under different conditions. Films deposited at 5x10-8 Torr exhibited high optical transparency (90%) and conductivity (~104 S/m). Films deposited at O2 pressures below 1x10-5 Torr were conductive (~104 S/m), magnetic (up to 480 emu/cc), and optically transparent, while the ones above 1x10-5 Torr were optically transparent but insulating and non-magnetic. Changes in the cation stoichiometry showed the films’ transition from being metallic to semiconducting with decreasing Fe content relative to the Lanthanides. However, when a very iron-rich film was annealed through several heating and cooling cycles in low vacuum, the film evolved into a semiconductor that was stable in ambient conditions and showed very high conductivity (2.8x105 S/m) and room temperature magnetism (380 emu/cc). The PLD deposited films were utilized as the ferromagnetic layer for magneto-electric coupling with bismuth ferrite as well as a top electrode for bismuth ferrite capacitors. A giant magneto-resistance (GMR) device made from the Fe-Tb-Dy-oxide and bismuth ferrite showed evidence of magneto-electric coupling at room temperature. The discovery of this oxide not only introduces new materials physics that could be explored and exploited to engineer new multifunctional materials, but the oxide itself proves to be very promising for spintronics device applications.
Book Synopsis Molecular Beam Epitaxy by : Mohamed Henini
Download or read book Molecular Beam Epitaxy written by Mohamed Henini and published by Newnes. This book was released on 2012-12-31 with total page 745 pages. Available in PDF, EPUB and Kindle. Book excerpt: This multi-contributor handbook discusses Molecular Beam Epitaxy (MBE), an epitaxial deposition technique which involves laying down layers of materials with atomic thicknesses on to substrates. It summarizes MBE research and application in epitaxial growth with close discussion and a ‘how to’ on processing molecular or atomic beams that occur on a surface of a heated crystalline substrate in a vacuum.MBE has expanded in importance over the past thirty years (in terms of unique authors, papers and conferences) from a pure research domain into commercial applications (prototype device structures and more at the advanced research stage). MBE is important because it enables new device phenomena and facilitates the production of multiple layered structures with extremely fine dimensional and compositional control. The techniques can be deployed wherever precise thin-film devices with enhanced and unique properties for computing, optics or photonics are required. This book covers the advances made by MBE both in research and mass production of electronic and optoelectronic devices. It includes new semiconductor materials, new device structures which are commercially available, and many more which are at the advanced research stage. Condenses fundamental science of MBE into a modern reference, speeding up literature review Discusses new materials, novel applications and new device structures, grounding current commercial applications with modern understanding in industry and research Coverage of MBE as mass production epitaxial technology enhances processing efficiency and throughput for semiconductor industry and nanostructured semiconductor materials research community
Book Synopsis The Synthesis, Characterisation and Application of Transparent Conducting Thin Films by : M. R. Waugh
Download or read book The Synthesis, Characterisation and Application of Transparent Conducting Thin Films written by M. R. Waugh and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Transparent conducting thin films of metal oxides, doped metal oxides, and carbon nanotubes (CNTs), have been produced using various deposition techniques, including: Aerosol Assisted Chemical Vapour Deposition (AACVD), Atmospheric Pressure Chemical Vapour Deposition (APCVD), and Spray Coating. The resultant thin films were tested for their performance in a number of applications, including: Low emissivity ('Low-E') glazing, photovoltaic electrode materials, gas sensing and photocatalysis. AACVD was shown as a viable, and attractive, deposition technique for the synthesis of tin oxide, and doped tin oxide thin films, which allows for controllable doping levels, crystallinity, and surface structure. The tailoring of these physical attributes allows for enhanced performance of the functional properties of the films, whereby, a lower growth temperature produced highly transparent, highly conductive coatings with a low haze value for 'Low-E' applications, whereas, higher growth temperatures produced the high electrical conductivity, transparency, and light scattering properties required for high performance electrodes in thin film photovoltaics. In addition, a dual coating methodology was developed using both AACVD, and APCVD, to grow tin oxide thin films in a rapid timescale, but with modified surface structures showing changes to the short range waviness, kurtosis, and the surface area. Growth of carbon nanotubes, using CVD, was investigated over a range of metal catalysts, with varying Pauling electronegativity values, and over a range of temperature, methane, and hydrogen conditions. A growth mechanism has been postulated, whereby, the electronegativity of the metal catalyst, and the solubility and diffusion of the carbon through that catalyst, affects the type and properties of the carbon structure produced. To the authors knowledge, this is the first reported growth of MWCNTs using a chromium solo-metal catalyst, and the first reported growth of the unique 'carbon nanofibres' which were produced using gold and silver metal catalysts. Functionalisation of SWCNTs using a microwave reflux process was shown to yield sulphonate and sulphone modified nanotubes, which are highly soluble in water and able to undergo spray coating to produce carbon nanotube, nanonet transparent conducting thin films. The functionalisation process was shown to be reversible upon heating of the modified nanotubes. AACVD has been deemed unable to produced doped zinc oxide transparent conducting films. However, undoped zinc oxide films were produced. They displayed a high photocatalytic action in the degredation of stearic acid, and a UV light induced superhydrophilicity. The modification and deposition techniques, established throughout this work, were utilised to form transparent, hybrid, metal oxide-CNT coatings, for gas sensing. The hybrid materials displayed enhanced response times to combustible target gases, which has been attributed to the catalytic effects of the exposed carbon nanotube surfaces; and to the spillover of adsorbed oxygen from the active nanotubes to the metal oxide surface.

This book was released on 2016 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: To begin this abstract, amorphous metal-oxide semiconductors offer the high carrier mobilities and excellent large-area uniformity required for high performance, transparent, flexible electronic devices; however, a critical bottleneck to their widespread implementation is the need to activate these materials at high temperatures which are not compatible with flexible polymer substrates. The highly controllable activation of amorphous indium gallium zinc oxide semiconductor channels using ionic liquid gating at room temperature is reported. Activation is controlled by electric field-induced oxygen migration across the ionic liquid-semiconductor interface. In addition to activation of unannealed devices, it is shown that threshold voltages of a transistor can be linearly tuned between the enhancement and depletion modes. Finally, the first ever example of transparent flexible thin film metal oxide transistor on a polyamide substrate created using this simple technique is demonstrated. Finally, this study demonstrates the potential of field-induced activation as a promising alternative to traditional postdeposition thermal annealing which opens the door to wide scale implementation into flexible electronic applications.
