Surface recombination velocity is an important factor for carrier recombination which dominates energy conversion efficiency in photocatalysts. We employed angle-lapped structure of SrTiO3 to estimate surface recombination velocities. We analyzed thickness dependence of the carrier lifetime by numerical modelling. Then we obtained more accurate values for the surface recombination velocities compared with the previous study.
