The field of thermoelectrics has grown dramatically in recent years. In particular new and novel materials research has been undertaken and device applications have increased. In spite of this resurgence of interest there are very few books available that outline the basic concepts in this field. Thus it is necessary that a book be written that encompasses the basic theory and introduces some of the resent research into improved materials for solid-state cooling and power generation. Therefore the aim of this book is threefold. First, to present the basic theory of thermoelectricity. Both...
