Abstract
The dielectric properties of self-supported tethered ferroelectric films were investigated. It was found that the films possess a dielectric constant of more than 2500 and a pyroelectric coefficient comparable with that of a single BaTiO3 crystal. The temperature and frequency dependence of the dielectric and pyroelectric properties suggest that some self-organization of the ferroelectric domains occurs. In this view one may expect that electromechanical (piezoelectric coupling) is responsible for the observed behavior.
