摘要:

We have investigated the interaction of Pt with single-crystalSrTiO3(001)and polycrystallineBa0.7Sr0.3TiO3thin films using photoemission spectroscopies. Significant band bending is caused by interface formation, determining the Schottky barrier height. We have depth profiled the band bending forBa0.7Sr0.3TiO3thin films, giving a direct measurement of the depletion depth and built-in potential. ©1997 American Institute of Physics.
