Va. Alyoshin et al., CRYSTAL-STRUCTURE PERFECTION AND DOMAIN-STRUCTURE REVEALING IN EPITAXIAL FERROELECTRIC THIN-FILMS, Radiation effects and defects in solids, 134(1-4), 1995, pp. 321-324
The deposition of epitaxial ferroelectric films with optically-perfect
surface and interface is shown to be possible. (Ba,Sr)TiO3/(001)MgO e
pitaxial films are c-domain and slightly self-polarized. The contrast
of domain boundary revealing in the films becomes worse as the crystal
structure perfection decreased. The role of film microvolumes with ze
ro spontaneous deformation arising upon influence of microstrains is d
iscussed.
