Shown are numerical results for the Kronig–Penney model. | |
|
The parameter a can be varied to quantify the strength of the periodic lattice potential. | |

The red curve shows the dispersion relation of the free electron gas, i.e. it's a parabolic function. | |
|
The blue curve shows the dispersion relation with band gaps. | |
|
The green curve shows the same dispersion relation in the reduced representation. | |
