Scanning Probe Microscopy Study of the Domain Growth in Relaxor Ferroelectrics

Liu X

Abstract

The aim of this paper was to study the domain growth of typical relaxor ferroelectric ceramics 0.9Pb(Mg1/3Nb2/3)O3-0.1PbTiO3. The topographic and elecric force images of samples were observed by Scanning Probe Microscopy taping mode and lift mode respectively The results demonstrate that the nano scale polar regions can switch to sub-micro domains under different dc voltages on the tip. Such process is carried out by 180° domain switching of micro dipoles along 111 axis in crystal under extra field.
