Book Synopsis Chemical Vapor Deposition Growth and Characterization of Two-Dimensional Hexagonal Boron Nitride by : Roland Yingjie Tay
Download or read book Chemical Vapor Deposition Growth and Characterization of Two-Dimensional Hexagonal Boron Nitride written by Roland Yingjie Tay and published by Springer. This book was released on 2018-06-20 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis focuses on the growth of a new type of two-dimensional (2D) material known as hexagonal boron nitride (h-BN) using chemical vapor deposition (CVD). It also presents several significant breakthroughs in the authors’ understanding of the growth mechanism and development of new growth techniques, which are now well known in the field. Of particular importance is the pioneering work showing experimental proof that 2D crystals of h-BN can indeed be hexagonal in shape. This came as a major surprise to many working in the 2D field, as it had been generally assumed that hexagonal-shaped h-BN was impossible due to energy dynamics. Beyond growth, the thesis also reports on synthesis techniques that are geared toward commercial applications. Large-area aligned growth and up to an eightfold reduction in the cost of h-BN production are demonstrated. At present, all other 2D materials generally use h-BN as their dielectric layer and for encapsulation. As such, this thesis lays the cornerstone for using CVD 2D h-BN for this purpose.
Book Synopsis Single Layer Nanomaterials by : Ashley L Gibb
Download or read book Single Layer Nanomaterials written by Ashley L Gibb and published by . This book was released on 2015 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: The design of novel nanomaterials with tunable geometries and properties has transformed chemistry and physics in recent years. In particular, recent advances in the isolation of two-dimensional films have inspired the exploration and development of stable, self-supporting single layer systems. Most notably graphene, a single layer of hexagonal sp2 carbon, has attracted interest due to intriguing electronic, optical, and mechanical properties. Hexagonal boron nitride (h-BN) is a closely related two- dimensional material, isoelectronic with graphene but often exhibiting very different electronic characteristics. The production of these monolayer materials has revealed exciting new properties that arise due to constrained geometry at the nanoscale. This dissertation explores the atomic scale properties of low-dimensional hexagonal nanomaterials, with a particular focus on hexagonal boron nitride (h-BN), graphene, and related materials. The synthesis processes for hexagonal boron nitride, graphene, nanotubes and nanoribbons will be discussed, with a particular emphasis on chemical vapor deposition. By controlling the number of layers in two-dimensional materials, we can tune their properties for new applications. The fabrication, characterization, and functionalization of additional low-dimensional nanomaterials including nanoribbons, nanotubes, and the composite materials that contain them will also be introduced. In nanoscale systems, material properties are heavily influenced by atomic structure and defects. This dissertation will discuss the investigation of h-BN and graphene at the atomic scale, with a particular emphasis on defects studied by atomic resolution transmission electron microscopy. Further probing the dynamics of these atomic defects includes in situ imaging and heating from room temperature up to 1000°C. Under these extreme conditions, novel defect structures and dynamics have been observed. In the coming years, these materials will continue to revolutionize the way we think about nanoscale materials, and are likely to be implemented into a variety of new and emerging technologies.

Book Synopsis The Growth and Characterization of Silicene, Germanene and Hexagonal Boron Nitride by : Adil Acun
Download or read book The Growth and Characterization of Silicene, Germanene and Hexagonal Boron Nitride written by Adil Acun and published by . This book was released on 2017 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: The discovery of graphene inspired the exploration of other 2D-materials. Silicon and germanium are elements with similar features as carbon. This lead to the fabrication of graphene's cousins, silicene and germanene, with similar properties as graphene. Notable differences are found in the structural and electronic properties of silicene and germanene versus graphene. Following the same reasoning, hexagonal boron-nitride was proposed as a graphene-like material. Unlike other 2D-materials, hexagonal boron-nitride is an insulator that may act as a buffer layer of 2D-materials. Therefore, the properties and synthesis of these materials are addressed in this thesis.

Book Synopsis Synthesis and Characterization of Bulk Single Crystal Hexagonal Boron Nitride from Metal Solvents by : Benjamin Clubine
Download or read book Synthesis and Characterization of Bulk Single Crystal Hexagonal Boron Nitride from Metal Solvents written by Benjamin Clubine and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Boron nitride is a purely synthetic material that has been known for over 150 years but only recently has sparked interest as a semiconductor material due to its potential in ultraviolet lasing and neutron detection. Thin-layer hexagonal boron nitride (hBN) is probably most attractive as a complementary material to graphene during its intense research endeavors. But for hBN to be successful in the realm of semiconductor technology, methods for growing large single crystals are critical, and its properties need to be accurately determined. In this study, hBN crystals were grown from metal solvents. The effects of soak temperature, soak time, source materials and their proportions on hBN crystal size and properties were investigated. The largest crystals of hBN measured five millimeters across and about 30 micrometers thick by precipitation from BN powder dissolved in a nickel-chromium solvent at 1700°C. High temperatures promoted outward growth of the crystal along the a-axis, whereas low temperatures promoted growth along the c-axis. Crystal growth at high temperatures also caused bulk hBN to adopt a triangular habit rather than a hexagonal one. A previously unreported method of synthesizing hBN was proven successful by substituting BN powder with elemental boron and a nitrogen ambient. XRD and Raman spectroscopy confirmed hBN from solution growth to be highly crystalline, with an 8.0 cm[superscript]-1 FWHM of the Raman peak being the narrowest reported. Photoluminescence spectra exhibited peaks mid-gap and near the band edge, suggesting impurities and defects in the hBN samples. However, high-purity reactants and post-growth annealing showed promise for synthesizing semiconductor-grade hBN. Several etchants were explored for defect-selective etching of hBN. A molten eutectic mixture of KOH/NaOH was the most effective defect-selective etchant of hBN at temperatures of 430-450°C for about one minute. The two prevalent hexagonal etch pit morphologies observed were deep, pointed-bottom pits and shallow, flat-bottom pits. TEM and SAED confirmed basal plane twists and dislocations in hBN crystals, but due to the highly anisotropic nature of hBN, their existence may be inevitable no matter the growth technique.

Book excerpt: A hexagonal boron nitride nanosheet (BNNS) is an atomic-thick 2D material that exhibits many interesting properties such as high chemical stability and excellent mechanical and thermal properties. In Chapter One, the authors introduce two methods for the exfoliation of BNNS from hexagonal boron nitride (hBN). Then, methodologies for the surface functionalisation and nanocomposite construction are demonstrated by two BNNS based nanocomposites. The catalytic performance of the BNNS based nanocomposites is also evaluated and discussed in detail. Chapter two evaluates the formation of rolled hexagonal boron nitride nano-sheets (h-BN nanoscrolls) on their unique morphology, magnetic properties and applications. Due to the high chemical and thermal stabilities, as well as atomically smooth surfaces with free of dangling bonds, hBN has been used as barriers, passivation and support layers in 2D electronic devices, to maximise the electrical and optical characterisation of 2D materials. However, there still remains a challenge in obtaining large-area and high-quality hBN film for real 2D electronic devices. Chapter Three focuses on chemical vapor deposition (CVD), a promising method to overcome these limitations. Chapter Four discusses how a boron doped armchair graphene ribbon has been shown by cyclic voltammetry to be a potential catalyst to replace platinum, however the reaction catalysed was not identified. The authors use density functional calculations to show the reaction catalysed is likely dissociation of HO2. Chapter Five reveals a novel and industrially feasible route to incorporate boron nitride nanoparticles (BNNPs) in radiation-shielding aerospace structural materials. Chapter Six deals with the preparation and characterisation of boron nitride nanotube (BNNT)-reinforced biopolyester matrices. The morphology, hydrophilicity, biodegradability, cytotoxicity, thermal, mechanical, tribological and antibacterial properties of the resulting nanocomposites are discussed in detail. Chapter Seven presents theoretical estimations regarding the compressive buckling response of single walled boron nitride nanotubes (SWBNNTs), which have a similar crystal structure as single walled carbon nanotubes (SWCNTs). Moreover, SWBNNTs have excellent mechanical, insulating and dielectric properties. Finally, Chapter Eight shows how the different exchange mechanisms can be distinguished and measured by studying solid films where part of the 3He is replaced by immobile Ne atoms. The authors also show how the formation energy of vacancies and vacancy tunneling frequency can be obtained from NMR studies at high temperature.
Book Synopsis Handbook of Physical Vapor Deposition (PVD) Processing by : D. M. Mattox
Download or read book Handbook of Physical Vapor Deposition (PVD) Processing written by D. M. Mattox and published by Cambridge University Press. This book was released on 2014-09-19 with total page 947 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers all aspects of physical vapor deposition (PVD) process technology from the characterizing and preparing the substrate material, through deposition processing and film characterization, to post-deposition processing. The emphasis of the book is on the aspects of the process flow that are critical to economical deposition of films that can meet the required performance specifications. The book covers subjects seldom treated in the literature: substrate characterization, adhesion, cleaning and the processing. The book also covers the widely discussed subjects of vacuum technology and the fundamentals of individual deposition processes. However, the author uniquely relates these topics to the practical issues that arise in PVD processing, such as contamination control and film growth effects, which are also rarely discussed in the literature. In bringing these subjects together in one book, the reader can understand the interrelationship between various aspects of the film deposition processing and the resulting film properties. The author draws upon his long experience with developing PVD processes and troubleshooting the processes in the manufacturing environment, to provide useful hints for not only avoiding problems, but also for solving problems when they arise. He uses actual experiences, called ""war stories"", to emphasize certain points. Special formatting of the text allows a reader who is already knowledgeable in the subject to scan through a section and find discussions that are of particular interest. The author has tried to make the subject index as useful as possible so that the reader can rapidly go to sections of particular interest. Extensive references allow the reader to pursue subjects in greater detail if desired. The book is intended to be both an introduction for those who are new to the field and a valuable resource to those already in the field. The discussion of transferring technology between R&D and manufacturing provided in Appendix 1, will be of special interest to the manager or engineer responsible for moving a PVD product and process from R&D into production. Appendix 2 has an extensive listing of periodical publications and professional societies that relate to PVD processing. The extensive Glossary of Terms and Acronyms provided in Appendix 3 will be of particular use to students and to those not fully conversant with the terminology of PVD processing or with the English language.

Book Synopsis Synthesis and Functionalization of Carbon and Boron Nitride Nanomaterials and Their Applications by : Kristopher John Erickson
Download or read book Synthesis and Functionalization of Carbon and Boron Nitride Nanomaterials and Their Applications written by Kristopher John Erickson and published by . This book was released on 2012 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carbon and boron-nitride based nanomaterials possess many exciting properties making them suitable for numerous applications spanning from electronics to advanced composites. However, these materials when synthesized often differ significantly from the idealized crystals usually considered theoretically. A thorough understanding of the structure of the materials as synthesized and how the resultant materials can be utilized for specific application purposes is required such that these applications can be effectively realized. To this end, the synthesis and characterization of carbon and boron-nitride based nanomaterials is undertaken with specific application purposes in mind. As a potential scalable synthetic route for graphene, graphene oxide (GO) and reduced graphene oxide are synthesized and characterized using atomic resolution electron microscopy. This elucidates their underlying structures revealing that the reduced form of GO does not resemble pristine graphene. The long-standing debate over the structure of GO is successfully ended with this study given the direct observation of the atomic structure of this material. To develop advanced composite materials, the functionalization of carbon and boron nitride nanotubes is undertaken. The characterization of their functionalization and incorporation within composite materials, specifically within a Kevlar polymer matrix, is presented to allow for the development of composites with significantly enhanced mechanical properties. Given a significant body of theoretical work paired with a single previous synthetic success, the synthesis of boron nitride nanoribbons is outlined. The first scalable synthesis of boron nitride nanoribbons is demonstrated resulting in long, consistent width, narrow, few-layer boron nitride nanoribbons which could be ideal for addressing these theoretical considerations. To establish a method for the synthesis of thin hexagonal-boron nitride (h-BN), the design of a specialized CVD system is described. The material resulting from this system is analyzed with methods including atomic resolution electron microscopy with the results informing future approaches for the synthesis of h-BN. Finally, high surface area boron nitride materials should be promising for hydrogen storage applications, especially if templated with a microporous scaffold. To this end, the first synthesis of a high surface area, microporous boron-nitride material is accomplished and the resultant surface areas of these materials are reported.
