Survey of the Theory of Electronic Conduction in Metals
In Chapter 1 we made no mention of the detailed mechanisms that lead to electronic conduction and associated thermoelectric effects. The general phenomenological equations (1.15) and (1.16) are equally valid for metals, semiconductors, or an ionized gas, and Onsager’s relations are correct for any of these. This book is concerned, however, only with metallic conductors, and our interest in thermoelectric phenomena is based on the belief that they can shed light on fundamental features of electronic energy levels and on the interaction of conduction electrons with their environment. To see this more clearly, we must now review briefly the elements of transport theory as it applies to these materials.
