Dynamics of plane domain walls in lead germanate and gadolinium molybdate

Influence of adsorbed surface layer on domain growth in the field produced by conductive tip of scanning probe microscope in lithium niobate

“…The termination of wall motion is observed in the limiting case of completely ineffective screening. [19][20][21][22] Let us consider the sideways growth of isolated circular domain of radius r(t) for current limited switching at the distances far from the tip.…”

Dynamics of Domains in NaNO2Crystals

“…For the moving wall it must be taken into account the existence of the depolarization field, which is not fully compensated by the external and bulk screening and acts as the driving field [7]. Jaśkiewicz et al [8] show that the depolarization field depends on the width of the domains, thus the walls of small domains in Fig.…”

Surface-screening mechanisms in ferroelectric thin films and their effect on polarization dynamics and domain structures

“…[68] Due the long-range nature of the depolarization effects, the incomplete surface screening of ferroelectric polarization strongly influences the domain structure and leads to its pronounced changes both near and relatively far from the surface, and affects phenomena such as domain wall pinning mechanisms at surfaces and interfaces, as well as nucleation dynamics, domain shape and period control in thin film under the open-circuited conditions, [70,71] in films placed between imperfect "real" electrodes with finite Tomas-Fermi screening length [72] or separated from the electrodes by ultra-thin dead layers [73] or physical gaps, [74] leads to the formation of closure domains near free surfaces in multiaxial ferroelectrics, [70,75,76] domain wall broadening in both uniaxial and multiaxial ferroelectrics [77,78] and crossover between different screening regimes of the moving domain wall -surface junctions.

“…Among the effects considered in Refs. [68,[70][71][72][73][74][75][76][77][78][79][80][81], the domain wall broadening seems universal and especially illustrative for the physical understanding of the role of surface screening charges on ferroelectric structures. [77] The broadening occurs because bound polarization and surface screening charges form an electric double layer, and the breaking of this layer by the domain wall induces stray depolarization field, which in turn changes the domain wall structure.…”
