Chapter IV electrical conductance in dielectric solids

One of the prerogatives of the authors of any review is the choice of emphasis on those subjects in which the authors are particularly interested. The material covered here reflects, to some extent, just such a preference. The sheer quantity of literature published during the year 1963 which could be included under this general title precludes any completely general coverage in a reasonable-sized review. Hence, a selection was based upon a supposition of the interests of the readers of this volume. On this basis, the strongest interest was centered on materials generally considered as dielectrics and on theory most applicable to dielectric materials. The metals, as well as other materials exhibiting metallic-like behavior, were in general not included. Likewise, no coverage was extended to the so-called wide-band semiconductors such as silicon and germanium on the assumption that adequate coverage of this subject is a separate work to be found in other sources. The intermetallic semiconductors were excluded on the same principle.
