Presents a simple qualitative model for the Stark Ladder spectrum based on the concept of a local band. The predictions of the model are supported by a numerical computation of the energy spectrum and wavefunctions for a finite one-dimensional model crystal potential. The results clearly show how a Stark Ladder develops when the potential difference applied to the crystal exceeds a given threshold value.
