Kurzfassung englisch:
Lanthanum-strontium manganite (La0.8Sr0.2MnO3, LSMO) is a perovskite oxide used as a cathode material in solid oxide fuel cells. To gain deeper insights into the reaction mechanisms, it is important to understand the structure of the surface at the atomic scale. To this end, atomically flat single-crystalline LSMO thin films were grown on Nb-doped SrTiO3 (001) substrates via pulsed laser deposition (PLD). The as-grown films were transferred in UHV from the PLD chamber to a surface science system. Studying the LSMO (001) surface by STM and LEED unveils various and unusual (cubic quasi-periodic) surface structures. They depend on the oxygen chemical potential upon annealing and termination of the surface (Mn or La/Sr).
