Book Synopsis Semiconductor Thermoelectric Generators by : Wolfgang R. Fahrner
Download or read book Semiconductor Thermoelectric Generators written by Wolfgang R. Fahrner and published by Trans Tech Publications Ltd. This book was released on 2009-07-22 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is well-known that fossil fuels are being rapidly depleted, and that atomic power is rejected by many people. As a consequence, there is a strong trend towards alternative sources such as wind, photovoltaics, solar heat and biomass. Strangely enough, quite another power source is generally neglected: namely, the thermoelectric generator (a device which converts heat, i.e. thermal energy, directly into electrical energy). The reason for this neglect is probably the low conversion efficiency, which is of the order of a few percent at most. However, there are two arguments in favor of the thermoelectric generator. Firstly, we might in effect be at the same point as we were in the early stages of photovoltaics use (it was only in 1954 that the first attractive solar cells, with efficiencies of around 4% were produced). Today, even large modules attain First 10% fixed. Secondly, the potential applications of thermoelectric generators are very tempting. Wherever heat is generated, it is amenable to electrical conversion. Energy harvesting via a thermoelectric generator may be accompanied by a further benefit: The use of a solar module inevitably leads to a drastic temperature rise. A thermoelectric generator reduces the temperature rise and therefore offers a double benefit.

Book Synopsis The Physics of Thermoelectric Energy Conversion by : Julian Goldsmid
Download or read book The Physics of Thermoelectric Energy Conversion written by Julian Goldsmid and published by Morgan & Claypool Publishers. This book was released on 2017-05-02 with total page 145 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book outlines the principles of thermoelectric generation and refrigeration from the discovery of the Seebeck and Peltier effects in the nineteenth century through the introduction of semiconductor thermoelements in the mid-twentieth century to the more recent development of nanostructured materials. It is shown that the efficiency of a thermoelectric generator and the coefficient of performance of a thermoelectric refrigerator can be related to a quantity known as the figure of merit. The figure of merit depends on the Seebeck coefficient and the ratio of the electrical to thermal conductivity. It is shown that expressions for these parameters can be derived from the band theory of solids. The conditions for favourable electronic properties are discussed. The methods for selecting materials with a low lattice thermal conductivity are outlined and the ways in which the scattering of phonons can be enhanced are described. The application of these principles is demonstrated for specific materials including the bismuth telluride alloys, bismuth antimony, alloys based on lead telluride, silicon-germanium and materials described as phonon-glass electron-crystals. It is shown that there can be advantages in using the less familiar transverse thermoelectric effects and the transverse thermomagnetic effects. Finally, practical aspects of thermoelectric generation and refrigeration are discussed. The book is aimed at readers who do not have a specialised knowledge of solid state physics.

Book Synopsis CRC Handbook of Thermoelectrics by : D.M. Rowe
Download or read book CRC Handbook of Thermoelectrics written by D.M. Rowe and published by CRC Press. This book was released on 2018-12-07 with total page 720 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thermoelectrics is the science and technology associated with thermoelectric converters, that is, the generation of electrical power by the Seebeck effect and refrigeration by the Peltier effect. Thermoelectric generators are being used in increasing numbers to provide electrical power in medical, military, and deep space applications where combinations of their desirable properties outweigh their relatively high cost and low generating efficiency. In recent years there also has been an increase in the requirement for thermoelectric coolers (Peltier devices) for use in infrared detectors and in optical communications. Information on thermoelectrics is not readily available as it is widely scattered throughout the literature. The Handbook centralizes this information in a convenient format under a single cover. Sixty of the world's foremost authorities on thermoelectrics have contributed to this Handbook. It is comprised of fifty-five chapters, a number of which contain previously unpublished material. The contents are arranged in eight sections: general principles and theoretical considerations, material preparation, measurement of thermoelectric properties, thermoelectric materials, thermoelectric generation, generator applications, thermoelectric refrigeration, and applications of thermoelectric cooling. The CRC Handbook of Thermoelectrics has a broad-based scope. It will interest researchers, technologists, and manufacturers, as well as students and the well-informed, non-specialist reader.

Book Synopsis Superconducting Thermoelectric Generator by :
Download or read book Superconducting Thermoelectric Generator written by and published by . This book was released on 1994 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thermoelectricity is produced by applying a temperature differential to dissimilar electrically conducting or semiconducting materials, thereby producing a voltage that is proportional to the temperature difference. Thermoelectric generators use this effect to directly convert heat into electricity; however, presently-known generators have low efficiencies due to the production of high currents which in turn cause large resistive heating losses. Some thermoelectric generators operate at efficiencies between 4% and 7% in the 800° to 1200°C range. According to its major aspects and bradly stated, the present invention is an apparatus and method for producing electricity from heat. In particular, the invention is a thermoelectric generator that juxtaposes a superconducting material and a semiconducting material - so that the superconducting and the semiconducting materials touch - to convert heat energy into electrical energy without resistive losses in the temperature range below the critical temperature of the superconducting material. Preferably, an array of superconducting material is encased in one of several possible configurations within a second material having a high thermal conductivity, preferably a semiconductor, to form a thermoelectric generator.

Book Synopsis Quantum Physics of Semiconductor Materials and Devices by : Debdeep Jena
Download or read book Quantum Physics of Semiconductor Materials and Devices written by Debdeep Jena and published by Oxford University Press. This book was released on 2022-05-26 with total page 896 pages. Available in PDF, EPUB and Kindle. Book excerpt: ”Quantum Phenomena do not occur in a Hilbert space. They occur in a laboratory”. - Asher Peres Semiconductor physics is a laboratory to learn and discover the concepts of quantum mechanics and thermodynamics, condensed matter physics, and materials science, and the payoffs are almost immediate in the form of useful semiconductor devices. Debdeep Jena has had the opportunity to work on both sides of the fence - on the fundamental materials science and quantum physics of semiconductors, and in their applications in semiconductor electronic and photonic devices. In Quantum Physics of Semiconductors and Nanostructures, Jena uses this experience to make each topic as tangible and accessible as possible to students at all levels. Consider the simplest physical processes that occur in semiconductors: electron or hole transport in bands and over barriers, collision of electrons with the atoms in the crystal, or when electrons and holes annihilate each other to produce a photon. The correct explanation of these processes require a quantum mechanical treatment. Any shortcuts lead to misconceptions that can take years to dispel, and sometimes become roadblocks towards a deeper understanding and appreciation of the richness of the subject. A typical introductory course on semiconductor physics would then require prerequisites of quantum mechanics, statistical physics and thermodynamics, materials science, and electromagnetism. Rarely would a student have all this background when (s)he takes a course of this nature in most universities. Jena's work fills in these gaps and gives students the background and deeper understanding of the quantum physics of semiconductors and nanostructures.
Book Synopsis Radioisotope Power Systems by : National Research Council
Download or read book Radioisotope Power Systems written by National Research Council and published by National Academies Press. This book was released on 2009-08-14 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spacecraft require electrical energy. This energy must be available in the outer reaches of the solar system where sunlight is very faint. It must be available through lunar nights that last for 14 days, through long periods of dark and cold at the higher latitudes on Mars, and in high-radiation fields such as those around Jupiter. Radioisotope power systems (RPSs) are the only available power source that can operate unconstrained in these environments for the long periods of time needed to accomplish many missions, and plutonium-238 (238Pu) is the only practical isotope for fueling them. Plutonium-238 does not occur in nature. The committee does not believe that there is any additional 238Pu (or any operational 238Pu production facilities) available anywhere in the world.The total amount of 238Pu available for NASA is fixed, and essentially all of it is already dedicated to support several pending missions-the Mars Science Laboratory, Discovery 12, the Outer Planets Flagship 1 (OPF 1), and (perhaps) a small number of additional missions with a very small demand for 238Pu. If the status quo persists, the United States will not be able to provide RPSs for any subsequent missions.
