Abstract
The authors adapt the split-step Fourier transform (SSFFT) algorithm to the problem of calculating the energy band diagrams and associated wavefunctions of solid-state lattices. The analysis is accompanied with a study of the accuracy of the technique in several test cases. They conclude from these calculations that the SSFFT method can be applied to a wide variety of solid-state physical problems.Keywords
