The Kronig-Penney Model
The Kronig-Penney Model
The Kronig–Penney model is a simple, idealized quantum-mechanical system that consists of an infinite periodic array of square potential barriers. It is often used as a pedagogical model to illustrate how periodic potentials can lead to the formation of electronic energy bands and band gaps. Thanks to the simplicity of the model, it is possible to solve for the band structure exactly, and this solution is shown in this Demonstration.
