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.
This second edition is a comprehensive introduction to all aspects
of thermoelectric energy conversion. It covers both theory and
practice. The book is timely as it refers to the many improvements
that have come about in the last few years through the use of
nanostructures. The concept of semiconductor thermoelements led to
major advances during the second half of the twentieth century,
making Peltier refrigeration a widely used technique. The latest
materials herald thermoelectric generation as the preferred
technique for exploiting low-grade heat. The book shows how
progress has been made by increasing the thermal resistivity of the
lattice until it is almost as large as it is for glass. It points
the way towards the attainment of similar improvements in the
electronic parameters. It does not neglect practical
considerations, such as the desirability of making thermocouples
from inexpensive and environmentally acceptable materials. The
second edition was extended to also include recent advances in
thermoelectric energy conversion, particularly the production of
bulk nanostructures, new materials with higher thermoelectric
figures to use the possibility of large scale thermoelectric
generation, as part of the worldwide strategy for making better use
of energy resources. This book guides the newcomer towards the
state of the art and shows the principles for further advancement
to those who are already familiar with the subject. The author has
been able to draw on his long experience to cover the science and
technology in a balanced way while drawing on the expertise of
others who have made major contributions to the field.
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.

Introduction to Thermoelectricity is the latest work by Professor
Julian Goldsmid drawing on his 55 years experience in the field.
The theory of the thermoelectric and related phenomena is presented
in sufficient detail to enable researchers to understand their
observations and develop improved thermoelectric materials. The
methods for the selection of materials and their improvement are
discussed. Thermoelectric materials for use in refrigeration and
electrical generation are reviewed. Experimental techniques for the
measurement of properties and for the production of thermoelements
are described. Special emphasis is placed on nanotechnology which
promises to yield great improvements in the efficiency of
thermoelectric devices. Chapters are also devoted to transverse
thermoelectric effects and thermionic energy conversion, both
techniques offering the promise of important applications in the
future.
