Summary

The results of Chap. 6 are generalized to three-dimensional tetravalent real solids, which are characterized mainly by two dimensionless parameters: the polarity index, ap, and the metallicity index, am. Depending on their values, we may have metallic or covalent or ionic behavior (see Fig. 7.4). The important concepts of holes, mass tensors, electronic and phononic DOS, impurity levels in the gap, and doping are introduced and/or examined. Tables of values of important quantities for various semiconductors are given.
