The k · p finite difference method is popular to calculate the band structure of semiconductors and their heterostructures. However, the effect of the step length in the differential process on the band structure is not clear yet. A comparative study between the k · p finite difference method and the bond orbital model is then made. With the optimum step length, one monolayer spacing along the growth direction, the calculated band structure of the k · p finite difference method is almost as accurate as that of the bond orbital model.
