Introduction to the Physics of Semiconductor Devices
Conclusions drawn from the Kronig-Penney model
- the Kronig-Penney model is an infinit, one-dimensional periodic chain of quantum wells
- applying Bloch's theorem, the Kronig-Penney model describes the formation of energy bands
separated by bandgaps
Left: Quasi-free electron in a periodic potential.
Right: Formation of the bandgap if the potential is applied.
