Abstract

The spatial distribution of the spontaneous polarization in LiNbO₃may be changed by proton-exchange. The treatment of this crystal in benzoic acid causes the appearance of a layer of reversed-direction spontaneous polarization near the z⁺-surface. We have investigated proton-exchanged LiNbO₃utilizing both ferroelectric electron emission (FEE) and the Surface Laser Intensity Modulation Method (SLIMM) to measure the spatial distribution of spontaneous polarization. The FEE diminished sharply in benzoic acid-treated samples. SLIMM showed that the proton-exchange treatment caused reversal of the direction of spontaneous polarization in a layer about 1.2µm thick on the z⁺-surface. No reversal occurred on the z^--surface.
