The energy bands of electrons in a one‐dimensional periodic potential consisting of two different rectangular barriers and wells per period are calculated. The variation of the energy band structure as a function of the size of the wells in each period is presented. The results can be used to obtain the energy scheme of a superlattice with the layer structure of this model. The method used can be applied to solve for the band structure of an electron in a periodic potential consisting of multiple barriers per period.
