Abstract
Cleavage surfaces perpendicular to the polarization vector of the ferroelectric crystals guanidinium uranyl sulfate hydrate (GUSH), guanidinium aluminum sulfate hydrate (GASH) and triglycine sulfate (TGS) decorated with gold, tellurium and silver chloride were observed and compared with the patterns obtained in the non-ferroelectric crystals guanidinium zinc sulfate (GZnS), NaCl and LiF. It was shown that, while some of the decoration structures reproduce the shape of the ferroelectric domains, others are cleavage steps or fracture structures which are not always related to the presence of domains. Although decoration is a useful tool for the detection of ferroelectric domains in materials that are unstable under the conditions prevailing in the electron microscope, the decoration patterns should be carefully analyzed and the relationship between the cleavage plane, cleavage direction and the orientation of the electric polarization vector should be taken into account in order to distinguish between cleavage, fracture and domain structures.
