摘要:
The epitaxial BiFeO3 films on different substrates were prepared by metal organic chemical vapor deposition (MOCVD). The ferroelectric properties of the films were controlled by Piezoresponse Force Microscopy (PFM). The isopiestic post-annealing of the film inside the ceramic container made of BiFeO3 and Bi2Fe4O9 phase mixture was proposed to control the film stoichiometry.
