Phase Diagram of Thin Film Oxides Growth by Pulsed Laser Deposition

ORAL

Abstract

We present a qualitative analysis of the microscopic thermo-dynamical origin of thin film oxides growth using the pulsed laser deposition technique. A phase diagram containing different growth mechanisms has been established. By tuning growth parameters experimentally in [LaSr]MnO3/SrTiO3 system, we observe an excellent fit of thin film morphologies to our growth phase diagram. Our results offer guidance on controlling morphology, stoichiometry and crystallinity of oxides thin films.
