摘要：

A new approach to the growth of complex oxide films free of any secondary phases using the volatile component was developed. The technique consists in a self-tuning of the oxide film composition during the growth due to the evaporation of the excess PbO. It was successfully used for the MOCVD growth of very smooth single phase La1-xPbxMnO3 (x=0.1-0.6) films on perovskite substrates and MgO at a deposition rate of similar to1 mum h(-1). High quality of the films was explained by the presence of quasi-liquid PbO surface layer activating the surface diffusion during the growth. (C) 2001 Published by Elsevier Science Ltd.
