摘要：

A simple computer program is presented, well within the capability of sophomore students, which solves the Schrodinger equation for a "lattice" of up to 12 potential wells, and which demonstrates many features important in a discussion of semiconductor physics-energy bands, impurity states, amorphous effects, negative effective mass. The ability to present material like this to students computationally may well have a profound effect on what is taught in future physics curriculums.
