Abstract

The method of the micro-domains formation in photorefractive crystals near the illuminated area polarized due to the screening effects is developed. The micro-domain shape and physical properties are studied in the phenomenological Ginsburg-Landau-Devonshire theory framework with respect to the semiconductor properties of ferroelectric medium. The spontaneous electric induction distribution in the micro-domain is shown to depend on the surface charge distribution on the boundary between illuminated area and the other system. Owing to the surface density peculiarities the transversal micro-domain size is revealed to be much smaller than longitudinal one.
