Abstract

Abstract : The photovoltage and lifetime of the photo‐excited carriers at the SrTiO3 surface drastically change with the SrRuO3 overlayers, as element specifically tracked by time‐resolved core‐level photoemission spectroscopy. The results show that the optical responses of oxide semiconductor heterostructures are designed by the band alignment scheme and they are tailored by the film growth.
