This book was released on 2013 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lead chalcogenides, most notably lead selenide (PbSe) and lead telluride (PbTe), have become an active area of research due to their thermoelectric properties. The high figure of merit (zT) of these materials has brought much attention to them, due to their ability to convert waste heat into electricity. Recent efforts, such as applying pressure or doping, have shown an increase in thermoelectric efficiency. Variation in application and synthesis conditions gives rise to a need for analysis of structural, electronic, and mechanical properties of these materials at different pressures. In addition to the NaCl structure at ambient conditions, lead chalcogenides have a dynamic orthorhombic (Pnma) intermediate pressure phase and a higher pressure, yet stable, CsCl phase. By altering the lattice constant, the application of external pressure is simulated; this has notable effects on total ground-state energy, band gap, and structural phase. Using the Projector Augmented Wave (PAW) Method and the Generalized Gradient Approximation (GGA) in Density Functional Theory (DFT), the phase transition pressures are calculated by finding the differences in enthalpy from total energy calculations. For each phase, elastic constants, bulk modulus, shear modulus, and Young's modulus are calculated, and the NaCl phase is studied with typical dopants, both n-type (Bi, In, and I) and p-type (Na and Tl). Pugh's ratio is employed to give insight on the brittleness of the materials and phases studied. In addition to structural and mechanical properties, the band structure and density of states are analyzed at varying pressures, paying special note to thermoelectric implications. The results presented here will be useful to guide future experiments toward the search for structurally stable thermoelectric materials. Several mechanical properties predicted here are ready to be confirmed by experimental works.

Download or read book Thermoelectrics Handbook written by D.M. Rowe and published by CRC Press. This book was released on 2018-10-03 with total page 1008 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ten years ago, D.M. Rowe introduced the bestselling CRC Handbook of Thermoelectrics to wide acclaim. Since then, increasing environmental concerns, desire for long-life electrical power sources, and continued progress in miniaturization of electronics has led to a substantial increase in research activity involving thermoelectrics. Reflecting the latest trends and developments, the Thermoelectrics Handbook: Macro to Nano is an extension of the earlier work and covers the entire range of thermoelectrics disciplines. Serving as a convenient reference as well as a thorough introduction to thermoelectrics, this book includes contributions from 99 leading authorities from around the world. Its coverage spans from general principles and theoretical concepts to material preparation and measurements; thermoelectric materials; thermoelements, modules, and devices; and thermoelectric systems and applications. Reflecting the enormous impact of nanotechnology on the field-as the thermoelectric properties of nanostructured materials far surpass the performance of conventional materials-each section progresses systematically from macro-scale to micro/nano-scale topics. In addition, the book contains an appendix listing major manufacturers and suppliers of thermoelectric modules. There is no longer any need to spend hours plodding through the journal literature for information. The Thermoelectrics Handbook: Macro to Nano offers a timely, comprehensive treatment of all areas of thermoelectrics in a single, unified reference.

Available in PDF, EPUB and Kindle. Book excerpt: The search to replace the toxic lead telluride (PbTe) alloys for thermoelectric applications in power generation has led to intensive studies of other telluride-based chalcogenide semiconductors. In this context, the binary SnTe has re-emerged over the last years as a promising candidate due to its rock-salt structure and electronic valence band structure similar to PbTe. Indium is a particularly intriguing dopant for SnTe as it leads to the appearance of a resonant level and superconductivity. Another noteworthy chalcogenide semiconductor, InTe has been recently shown to harbor promising thermoelectric properties due to its remarkably very low lattice thermal conductivity. The lack of detailed studies of its transport properties makes this compound a promising area of research in the field of thermoelectrics. In this work, we report on a detailed experimental and theoretical investigations of the transport properties of these two Te-based chalcogenides (XTe; X = Sn, In) in a wide range of temperatures (2 - 800 K). In a first part, the influence of indium on the transport properties of Sn1.03-xInxTe (0 ≤ x ≤ 40 %) is considered. The experimental results are supported by electronic band structure calculations performed using the Korringa-Kohn-Rostoker method with the coherent potential approximation (KKR-CPA). Both experimental and theoretical results demonstrate the resonant nature of In in Sn1.03Te with an optimum doping level of 2% giving the highest thermopower value for this system. Low-temperature transport properties measurements further highlight the complex evolution of the transport properties for low In contents. Investigations performed on InTe were performed on both single-crystalline and polycrystalline samples. A large single crystal of InTe was grown by the vertical Bridgman method. The possibility to control the defect concentration in InTe was considered though the saturation annealing method, carried out on the In-rich and Te-rich side of the solidus. Comparable to the peak ZT of ~ 0.7 at 780 K achieved in single-crystalline InTe within the ab plane, a maximum ZT of ~ 0.9 at 710 K was obtained in polycrystalline InTe.

Available in PDF, EPUB and Kindle. Book excerpt: The search for cleaner, cheaper, smaller and more efficient energy technologies has to a large extent been motivated by the development of new materials. The aim of this collection of articles is therefore to focus on what materials-based solutions can offer and show how the rationale design and improvement of their physical and chemical properties can lead to energy-production alternatives that have the potential to compete with existing technologies. In terms of alternative means to generate electricity that utilize renewable energy sources, the most dramatic breakthroughs for both mobile (i.e., transportation) and stationary applications are taking place in the fields of solar and fuel cells. And from an energy-storage perspective, exciting developments can be seen emerging from the fields of rechargeable batteries and hydrogen storage.
