Solution of the Schrödinger Equation for Four Specific Problems a potential free space in the positive x-direction. In other words, it is assumed that no “wall,” i.e., no potential barrier (.), restricts the propagation of the electron wave. The potential energy . is then zero and the Schrödinger equation (3.1) assumes the following form: ..

Energy Bands in CrystalsWe are now in a position to make additional important statements which contribute considerably to the understanding of the properties of crystals. For this we plot the energy versus the momentum of the electrons or, because of (4.8), versus the wave vector .. As before we first discuss the one-dimensional case.

In other words, the electron theory provides important fundamentals for a technology which is often considered to be the basis for modern civilization. A few examples will illustrate this.
