Polarization switching in perforated ferroelectric films

Abstract

The polarization switching in ferroelectric films of barium strontium titanate with a planar struc ture of interdigitated electrodes has been studied experimentally. The local polarization distribution in an interelectrode gap of these films in an applied electric field has been investigated using nonlinear optical microscopy. The polarization switching parameters of unperforated and perforated films have been com pared.
