A numerical investigation of the bulk photovoltaic tensor for a ferroelectric crystal is presented. The studies are based on a simple two‐dimensional LCAO model which preferably can be treated analytically. In contrast to previous studies, however, the complete band structure and wave vector dependence of the transition matrix elements are taken into account. This paper also reports the first numerical application of the R ‐vector concept which is recently developed for the intrinsic bulk photovoltaic effect.
