Na. Pertsev et al., DOMAIN-WALL AND INTRINSIC CONTRIBUTIONS TO THE DIELECTRIC RESPONSE OFEPITAXIAL FERROELECTRIC-FILMS, Microelectronic engineering, 29(1-4), 1995, pp. 135-140
Domain-wall and intrinsic contributions to the dielectric response of
epitaxial ferroelectric thin films are analysed theoretically. It is s
hown that the contribution caused by translational vibrations of 900 d
omain walls must be substantial in common heterostructures. The influe
nce of internal stresses existing in the strained epitaxy on the intri
nsic dielectric response is considered for single-domain films.
