Abstract:

A comparative analysis of polarization-switching kinetics in single crystals of congruent and stoichiometric lithium tantalate LiTaO3 is carried out by recording a sequence of instantaneous domain configurations (optical visualization of the evolution of the domain-structure) and the switching current simultaneously. A new mechanism of fast kinetics of domains in congruent lithium titanate due to the growth of steps formed during domain coalescence is discovered experimentally and studied with the help of computer simulation. Additional information on the domain kinetics in stoichiometric lithium tantalate is obtained on the basis of statistical analysis of the noise component of a switching current. A model is proposed for description of the jerky motion of domain walls. © 2002 MAIK "Nauka/Interperiodica".
