An idealized, one-dimensional model of a crystal which exhibits many of the basic features of the electronic structure of real crystals. Consider the potential energy V(x) of an electron illustrated in Fig. 1 with an infinite sequence of potential wells of depth −Vo and width a, arranged with a spacing b. The Schrödinger wave equation can be readily solved for such an arrangement to give electron energy as a function of wave number.
