Book excerpt: Various routes towards novel chlorogallium bis(alkoxides) and heteroleptic gallium alkoxides have been investigated. Compounds of the type, [GaCl(OR2)2] and [Ga(OR2)2(OR')] (R = CH2CH2NMe2, CH2CH2NEt2, CH2CH2CH2NMe2; R' = Me, Et, iPr, tBu), were synthesised using air sensitive methods and analysed by a variety of techniques. The chlorogallium bis(alkoxides) showed diastereotopic NMR splitting and in depth 1H NMR studies and DFT calculations were carried out on [GaCl(OCH2CH2CH2NMe2)2] to investigate the in situ ring conversion mechanism. Thermogravimetric analysis was employed to study the decomposition characteristics of the compounds, which were then used as single-source precursors towards gallium oxide thin films using aerosol-assisted chemical vapour deposition (AACVD). Amorphous, transparent films of Ga2O3 were deposited at 450 °C onto glass and quartz substrates. Subsequent annealing at 1000 °C gave crystalline films. Nitrogen-doped indium oxide films were deposited by AACVD via the in situ reaction of [In{NtBu(SiMe3)}3] and three equivalents of HOCH2CH2NMe2. The resultant films had a range of morphologies depending on solvent and temperature employed during the deposition. The cubic phase In2O3 films deposited had band gaps of ~2.9 eV suggesting nitrogen incorporation. These films were tested on steel and titanium substrates for their visible light water-splitting properties. Films were tested for their hydrogen production but limited activity as a photocatalyst was observed in the visible region. However, In2O3 nanoparticles produced using a solvothermal method and Ti- and Ta-doped In2O3 thin films grown via AACVD were tested for their gas sensing properties. Sensors were tested against reducing oxidising gases. The In2O3 nanoparticles showed the highest response to all gases, in particular ethanol. In2O3:Ta also showed a significant response to ethanol and smaller responses to other gases. Overall, novel precursors have been used as single-source precursors to main group oxide thin films, which were deposited via AACVD. Photocatalytic and gas sensing applications of these films have been explored.
Book Synopsis Synthesis, Chemical Vapour Deposition and Structural Studies of Group 13 Alkoxides by : C. E. Knapp
Download or read book Synthesis, Chemical Vapour Deposition and Structural Studies of Group 13 Alkoxides written by C. E. Knapp and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This work is concerned with the synthesis of precursors to group 13 oxide thin films, and the subsequent chemical vapour deposition (CVD) of group 13 mixed metal oxide films. Investigations into the mechanisms at work during their decomposition via various techniques including gas phase electron diffraction (GED) is also discussed. A wide variety of group 13 alkoxides have been synthesised and characterised and described in this thesis. Significant findings support previous investigations showing the reaction of trialkyl group 13 complexes [MR3] with an excess of a donor functionalised alcohol does not yield a group 13 bis(alkoxide). However, compounds of the type [Ga(OR)nCl3-n] (n = 1, 2) have been synthesised using direct routes from gallium amido precursors, which are also described herein. In addition a wide variety of novel group 13 precursors incorporating a mixture of ligands leading to enhanced properties, desirable for CVD are presented. The gas phase structures of the dimethylalkoxygallanes, [Me2GaOCH2CH2NMe2]2 and [Me2GaOCH2CH2OMe]2 have been obtained via gas-phase electron diffraction from studying the vapour produced upon heating. Ab initio molecular orbital calculations are presented for these compounds, as well as the gas phase structure of [Me2GaOtBu]2. Only the monomeric forms [Me2GaOCH2CH2NMe2] and [Me2GaOCH2CH2OMe] are observed in the gas phase with donor functionalised ligands, whereas the dimer [Me2GaOtBu]2 remains intact in the gas phase. Gallium oxide films were grown via AACVD using a variety of group 13 precursors. The films deposited were not oxygen deficient and little carbon contamination was observed, which is attributed to being a direct result of precursor design. Thin films of indium gallium oxide, and zinc gallium oxide were also produced from the in situ reactions of InMe3, GaMe3 and HOCH2CH2OMe (for GaxIn2-xO3) and ZnEt2, GaMe3 and HOCH2CH2OMe (for GaxZnyO) via AACVD on silica substrates.
Book Synopsis Precursor Chemistry of Advanced Materials by : Roland A. Fischer
Download or read book Precursor Chemistry of Advanced Materials written by Roland A. Fischer and published by Springer Science & Business Media. This book was released on 2005-09-29 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Material synthesis by the transformation of organometallic compounds (precursors) by vapor deposition techniques such as chemical vapor deposition (CVD) and atomic layer deposition (ALD) has been in the forefront of modern day research and development of new materials. There exists a need for new routes for designing and synthesizing new precursors as well as the application of established molecular precursors to derive tuneable materials for technological demands. With regard to the precursor chemistry, a most detailed understanding of the mechanistic complexity of materials formation from molecular precursors is very important for further development of new processes and advanced materials. To emphasize and stimulate research in these areas, this volume comprises a selection of case studies covering various key-aspects of the interplay of precursor chemistry with the process conditions of materials formation, particularly looking at the similarities and differences of CVD, ALD and nanoparticle synthesis, e.g. colloid chemistry, involving tailored molecular precursors.

Download or read book Nanomaterials via Single-Source Precursors written by Allen W. Apblett and published by Elsevier. This book was released on 2022-02-19 with total page 630 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nanomaterials via Single-Source Precursors: Synthesis, Processing and Applications presents recent results and overviews of synthesis, processing, characterization and applications of advanced materials for energy, electronics, biomedicine, sensors and aerospace. A variety of processing methods (vapor, liquid and solid-state) are covered, along with materials, including metals, oxides, semiconductor, sulfides, selenides, nitrides, and carbon-based materials. Production of quantum dots, nanoparticles, thin films and composites are described by a collection of international experts. Given the ability to customize the phase, morphology, and properties of target materials, this “rational approach to synthesis and processing is a disruptive technology for electronic, energy, structural and biomedical (nano)materials and devices. The use of single-source chemical precursors for materials processing technology allows for intimate elemental mixing and hence production of complex materials at temperatures well below traditional physical methods and those involving direct combination of elements. The use of lower temperatures enables thin-film deposition on lightweight polymer substrates and reduces damage to complex devices structures such as used in power, electronics and sensors. Discusses new approaches to synthesis or single-source precursors (SSPs) and the concept of rational design of materials Includes materials processing of SSPs in the design of new materials and novel devices Provides comprehensive coverage of the subject (materials science and chemistry) as related to SSPs and the range of potential applications

Book excerpt: Comprehensive Inorganic Chemistry II, Nine Volume Set reviews and examines topics of relevance to today’s inorganic chemists. Covering more interdisciplinary and high impact areas, Comprehensive Inorganic Chemistry II includes biological inorganic chemistry, solid state chemistry, materials chemistry, and nanoscience. The work is designed to follow on, with a different viewpoint and format, from our 1973 work, Comprehensive Inorganic Chemistry, edited by Bailar, Emeléus, Nyholm, and Trotman-Dickenson, which has received over 2,000 citations. The new work will also complement other recent Elsevier works in this area, Comprehensive Coordination Chemistry and Comprehensive Organometallic Chemistry, to form a trio of works covering the whole of modern inorganic chemistry. Chapters are designed to provide a valuable, long-standing scientific resource for both advanced students new to an area and researchers who need further background or answers to a particular problem on the elements, their compounds, or applications. Chapters are written by teams of leading experts, under the guidance of the Volume Editors and the Editors-in-Chief. The articles are written at a level that allows undergraduate students to understand the material, while providing active researchers with a ready reference resource for information in the field. The chapters will not provide basic data on the elements, which is available from many sources (and the original work), but instead concentrate on applications of the elements and their compounds. Provides a comprehensive review which serves to put many advances in perspective and allows the reader to make connections to related fields, such as: biological inorganic chemistry, materials chemistry, solid state chemistry and nanoscience Inorganic chemistry is rapidly developing, which brings about the need for a reference resource such as this that summarise recent developments and simultaneously provide background information Forms the new definitive source for researchers interested in elements and their applications; completely replacing the highly cited first edition, which published in 1973
