We have investigated the interaction of Pt with single-crystal SrTiO3(001) and polycrystalline Ba0.7Sr0.3TiO3 thin films using photoemission spectroscopies. Significant bandbending is caused by interface formation, determining the Schottky barrier height. We have depth profiled the bandbending for Ba0.7Sr0.3TiO3 thin films, giving a direct measurement of the depletion depth and built-in potential
