Abstract

The formation of very thin domain layers on the surface of multidomain lithium tantalate by heat treatment is observed by scanning nonlinear dielectric microscopy. A similar phenomenon of forming a very thin single-domain layer was also observed on the surface of periodically polarized lithium niobate single crystal. By measuring the thickness of the single-domain layers, the depth sensitivity of the scanning nonlinear dielectric microscope with submicron resolution was estimated.
