Abstract
A periodically domain-inverted KTiOPO4 crystal, in which inverted ferroelectric domains were produced by electric-field poling, has been studied using high-resolution x-ray scattering and diffraction imaging techniques. The degree of perfection of domain inversion as well as the periodic structure has been revealed in high-spatial-resolution images, and the periodic contrast is shown to arise largely from lattice distortions produced in the poled regions. The q(parallel to) dependence of intensity scattered from the domain-inverted structure can be described by a two-component line shape, one with a sharp nearly-pure-Gaussian line, the other with a broad pseudo-voigt-function profile. A high-angular-resolution method has been combined to elucidate the origin of the two-component profile. The diffuse scattering of the crystal truncation rod along q(perpendicular to) is observed to follow a power law q(perpendicular to)(-gamma) with gamma similar to 2.29 +/- 0.03 after poling compared with an average value of 2.05 +/- 0.03 before poling. Discussions of the electric-field poling and its consequence for the domain-inverted structure are presented in terms of the results of x-ray measurements. [S0163-1829(99)09921-X].
