内容記述 |
Local polarization and charge transfer at the interface between 7-unit cell-thick LaMnO3 (LMO) ultrathin films and substrates composed of Nb-doped (0.05 wt. %) and undoped SrTiO3 (STO) are examined by resonant surface x-ray diffraction. Notably, this photon-in photon-out technique allows us to simultaneously examine the valence distribution and local polarization with minimal radiation damage. Consistent with previous reports, Mn2t is observed at the interface. Furthermore, the degree of charge transfer is nearly unchanged by the 0.05 wt. % of Nb doping. In the middle of the LMO films, the valence of Mn is 3t. Local polarization estimated from the cation/anion displacements shows that the electric field points outward in the LMO films, and polarization is suppressed in the STO substrate region. |
