The Kronig-Penney model is a simple approximation of a solid. The potential consists of a periodic arrangement of delta functions, square well or Coulomb well potentials. By means of epitaxial growth techniques artificial semiconductor superlattices can be realized, which behave very similar to the assumptions of the Kronig-Penny model. To get better understanding of the Kroinig-Penney model, we provide written text, slides, homework assignments and access to the Periodic Potential Lab and the Bandstructure Tool that can be used to solve the homework assignments and investigate the particle dispersion relation as a function of the well geometry and well to well interactions.
