Coherent and incoherent d band dispersions in SrVO3

We have performed an angle-resolved photoemission spectroscopy study of SrVO3 thin films. Utilizing thin films prepared in situ, with well-defined and atomically flat surfaces, contributions from surface states centered at ∼-1.5 eV were dramatically reduced, enabling us to study the bulklike V3d sta...
