Available in PDF, EPUB and Kindle. Book excerpt: Electrical Conduction in Solid Materials (Physicochemical Bases and Possible Applications) investigates the physicochemical bases and possible applications of electrical conduction in solid materials, with emphasis on conductors, semiconductors, and insulators. Topics range from the interatomic bonds of conductors to the effective atomic charge in conventional semiconductors and magnetic transitions in switching semiconductors. Comprised of 10 chapters, this volume begins with a description of electrical conduction in conductors and semiconductors, metals and alloys, as well as interatomic bonds and the resistivity of magnetic conductors. Subsequent chapters focus on conventional semiconductors, including intrinsic semiconductors and binary and ternary compounds; compounds containing ordered or disordered atomic magnetic moments, showing paramagnetism of ferro-, ferri-, or antiferromagnetism; and magnetic and crystallographic transitions in switching semiconductors. Organic and inorganic insulators are also considered, along with possible applications of conductors, semiconductors, and insulators. Finally, the special magnetoelectric effects and magneto-optical effects of magnetic semiconductors are analyzed. This book will be a valuable resource for students of physical chemistry.

Available in PDF, EPUB and Kindle. Book excerpt: Since 1963 the Research Materials Information Center has been answering inquiries on the availability, preparation, and properties of ultrapure inorganic research specimens. It has been possible to do this with reasonable efficiency by searching an automated coded microfilm collection of the report and open literature and of data sheets and question naires provided by commercial and research producers of pure materials. With the growth of the collection to over 70,000 documents and the increase in the demand for more general background information, it has been necessary to compile bibliographies on an increasing variety of subjects. These have been used as indexes to the microfilmed documents for more efficient searching, and in the past distributed in response to individual requests. However, their size and number no longer permit so casual and uneconomic a method of distribution. The "ORNL Solid State Physics Literature Guides" is a practical alternative. Organization The subject organization of the bibliography is given by the Table of Contents. Each section is preceded by a collection of reviews, bibliographies, and "general" papers (i.e., those dealing with methods or equipment rather than single materials, or with such a wide variety of materials that no subsection was appropriate). Coverage is generally from 1960 to mid-1970. Emphasis is on inorganic materials.

This book was released on 2017 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of crystalline materials has played a prominent role in solid state physics, whose basic theories were formulated for crystalline matter. However, disordered materials are more abundant in nature than crystalline ones, and, moreover, many practical applications use materials which are weakly or strongly disordered, such as molecular crystals, glasses, plastic crystals, liquids, polymers, or liquid crystals. In glasses, for example, the arrangement of the constituent atoms or molecules lacks any long-range order. From a fundamental viewpoint, we still lack an understanding of the properties of disordered materials and of the glass transition: understanding the many fascinating issues related with disorder requires in fact the use of concepts that are far from the well-known solid-state concepts associated with periodicity. From an applied perspective, the intense research in disordered solids is driven by the technological importance of these materials in daily life. From an electrical viewpoint, disordered solids can conduct electricity by transport of either electrons or ions. In the first case, disordered materials display lower electrical conductivity than their crystalline counterparts, due to localization of conduction electrons due to disorder, so that electron hopping is the main charge transport mechanism. On the other hand, the same disorder may allow the diffusion of ions through interstitial sites; the ionic conductivity of disordered materials is normally higher than the crystalline counterparts. This thesis presents an experimental study of the conduction properties and molecular dynamics of molecular solids made of fullerene derivatives (C60Br6, C60(ONa)24) and of dinitrile molecules such as succinonitrile (C2H4(CN)2) and glutaronitrile (C3H6(CN)2). The studied materials display, depending on the case, mainly electronic, protonic, or ionic conduction. The thesis provides insight into the different possible types of charge conduction in organic molecular materials and on related physical processes such as space-charge relaxations. In C60Br6 we observe n-type electronic conduction below room temperature and a non-trivial phase behavior. The temperature dependence of the dc conductivity of this organic semiconductor is in agreement with the variable-range hopping model. C60(ONa)24 has even richer phase behavior. It is synthesized as a polycrystalline hydrate, and can be obtained as pure material by heating to high temperature. We show that while the pure material is an n-type (electron) semiconductor, exposing it to humid atmosphere leads to a dramatic conductivity enhancement due to charge transport through the hydration layers, which is likely mediated by a proton exchange mechanism as in bulk water and ice. We also show that the dc conductivity of the hydrate is strongly temperature dependent across the dehydration process, and that both pure and hydrated forms display a conductivity-related dynamic process associated with accumulation of electrons at grain boundaries. The presence of water has strong impact on such frequency-dependent charge-accumulation dynamics. We finally analyze the relaxation dynamics and the ionic conductivity of plastic-crystalline ionic conductors, in particular the plastic cocrystals of succinonitrile with glutaronitrile. In plastic crystals, the molecules occupy lattice sites but undergo free rotational motions about their centers of mass. We find that succinonitrile-glutaronitrile cocrystals are the first ever known plastic crystals to display a perfect correlation between the ion drift and the on-site reorientational dynamics. Doping the cocrystals with Li salts boosts the conductivity but breaks down this perfect correlation. This indicates that the rotation-drift correlation is only valid when charge transport is dominated by self-diffusion of molecular (dinitrile) ions, and that it is a consequence of the correlation between rotational and diffusional time scales.

Book excerpt: Humans first used carbon as chars from firewood in ritual paintings and primitive metallurgical processes. Natural forms of carbon have been known since antiquity, yet the knowledge of the carbon element in chemistry and its technical applications on a larger scale are a relatively recent development. The industrial revolution in Europe two centuries ago led the way to the numerous applications of these graphitic forms that are still used today. Graphite and Precursors features short tutorial articles on different topics related to the science and technology of carbons intended for engineers, students of Materials Science and scientists who are seeking a fundamental understanding without "reinventing the wheel." This first volume of the World of Carbon book series focuses on graphite and its precursors, including its origin and various implications. The basic properties of hexagonal graphite are developed, and several theoretical and experimental approaches explain why this crystalline solid is fascinating in solid state physics. Also featured are the numerous applications connected to thermal, mechanical and chemical graphites, as well as their various industrial uses in polycrystalline form. Finally, carbon precursors are introduced.

Available in PDF, EPUB and Kindle. Book excerpt: It is well known that solid carbons can be found in various guises with different forms of bulk phases (graphites, diamonds and carbynes) as well as more molecular forms (fullerenes,nanotubes and graphenes) resulting from recent discoveries. The cause of this rich polymorphism is analyzed in the first part of this book (chapters 1-5) with the propensity of carbon atoms for forming different types of homopolar chemical bonds associated with variable coordination numbers. Precursor organic molecules and parent compounds are also described to establish specific links with this rich polymorphism. Then in a second part (chapters 6-10) a comparative review of the main classes of bulk physical properties is presented. This approach emphasizes in particular the electronic behavior of (pi) polyaromatic systems organized in plane and curved atomic sheets. Finally in a third part (chapters 11-15) the surface and interface characteristics are introduced together with the texture and morphology of these multiscale carbon materials. An overview of the main field of applications is related showing the large use and interest for these solids.
