Recent publications on first principles electronic structure of ferroelectric domain walls (FE DW) in BiFeO3 show some variations concerning existence and magnitude of potential steps and band bending at pristine FE DW. We investigated these properties once more, trying to improve understanding by building on previous works in a systematic way. We also tested the hypothesis that FE DW modify the light absorption properties of BiFeO3.
