Abstract
The author of this chapter was not even born when the pioneering studies of the band structure of solids were being conducted by Slater, Wigner, Seitz, and others in the 1930’s, and he will not presume to paraphrase those early achievements. Suffice it to say that most of the ground rules for the description of energy bands in crystals were worked out rather thoroughly at that time. Despite having such early and respectable antecedents, band structure theory has enjoyed a period of hectic activity since about 1960—not only hectic, but also successful, since, over a wide area of solid-state theory, the balance has tipped from puzzlement to ennui in a single decade. Why? The answer is not to be sought on the back of any theorist’s envelope, but rather in two developments which indirectly facilitated and stimulated our theoretical understanding. These are the advent of high-speed computers and the refinement of experimental techniques, two aspects of the electronic revolution.
