SrMnO3 Film Grown by Pulsed Laser Deposition
Abstract: Two-step method through solid state reaction is used to synthesize high purity single phase po-lycrystalline SrMnO3 target. Then we use Pulsed Laser Deposition to grow SrMnO3 films on SrTiO3(001) substrates, we have tried different temperatures of substrate and different oxygen pressures during our experiment. Results show that with deposition temperature above 700 de-gree and oxygen pressure around 5 Pa, SrMnO3 film will grow with good crystallinity. X-Ray dif-fraction and synchrotron radiation X-Ray diffraction are measured here to identify the crystal structure. Epitaxy between film and substrate is confirmed and the orientation between film and substrate is SrMnO3(001)//SrTiO3(001), also phi scan shows that at in plane there is no rotation between film and substrate. X-ray photoelectron spectroscopy of Mn element reveal that in the film Mn have +3 and +4 two valence states, about 90 percentage of all the Mn are +4 valence. We speculate that the +3 valence state of Mn comes from defects in film or oxygen vacancy in it. Also XPS of O element is measured, spectroscopy shows that most of O element in film exist as lattice oxygen, another peak in spectroscopy may attribute to defect, absorbed oxygen or oxygen vacancy. Growth of SrMnO3 film establishes foundation for further study of SrMnO3.
