The charged domain wall is an ultrathin (typically nanosized) interface between two
domains; it carries bound charge owing to a change of normal component of spontaneous …

We considered the experimentally observed variety of domain shapes in crystals of lithium
niobate and lithium tantalate family. The shapes were classified, and their formation was …

The effects of domain wall shape instabilities and the formation of nanodomains in front of
moving walls obtained in various uniaxial ferroelectrics are discussed. Special attention is …

The proton-exchange process is an effective method of fabricating low-loss waveguides
based on LiNbO3 crystals. During proton-exchange, lithium is replaced by hydrogen and …

Hydrogen diffusion in proton-exchanged congruent LiNbO 3 single crystals is investigated in
the temperature range between 140 and 200 C. The proton-exchange process carried out in …

Pattern formation caused by self-organization is a fascinating phenomenon that appears in
biological, chemical, and physical systems. In ferroelectrics, although a variety of domain …

It was demonstrated that confocal Raman microscopy (CRM) could be used for domain
imaging in the calcium orthovanadate Ca3 (VO4) 2 single crystals. The domain contrast …

Swift heavy ion irradiation has been widely used to modify refractive indices of optical
materials for waveguide fabrication. In this work, we propose refractive index engineering by …

The results of an experimental study of the abnormal domain structure kinetics in lithium
niobate single crystals with a surface layer modified by soft proton exchange are presented …

This paper presents the results of the first experimental observation of polarization reversal
in the bulk of ferroelectric with a charged domain wall (CDW) under the action of an electric …
