Abstract
The local switching by conductive tip of scanning probe microscope was studied in the non-polar cuts of Ce-doped Sr0.61Ba0.39Nb2O6 single crystals after creation of the single-domain state. The switched domains possessed the egg-shaped heads and wedge-like tails. The dependences of lengths of the domain head and tail and width of the domain head on the voltage and pulse duration were derived. The start voltage for growth of the domain tail was revealed. The fast relaxation of the domain head and slow relaxation of the domain tail were observed. The model of the forward domain growth by step generation and kink motion was used for explanation of the experimental results. The obtained knowledge can be used for the domain engineering in ferroelectrics.
Highlights
The domain growth in ferroelectrics under the action of the local electric field produced by conductive tip of the scanning probe microscope (SPM) has been studied intensively due to applications of the ferroelectrics with engineered domain structures in optoelectronics and photonics [1,2,3,4]
We present the results of experimental study of tip-induced domain growth and its relaxation in the non-polar cuts of Ce-doped SBN61 single crystals after creation of single-domain state
The ZX distribution of the electric field, produced by SPM tip in contact with the nonpolar surface of SBN:Ce single crystals was calculated for the our experimental conditions (Fig. 2a) [27,28,29]
