WitrynaImaging methods of ferroelectric domains are based on the detection of surface charges in the noncontact mode of SFM and on the measurement of the piezoelectric response of a ferroelectric film to an external field applied by the tip in the SFM contact mode. This latter mode can be used for nondestructive evaluation of local … WitrynaThe dark field TEM image (Figure 5a) shows a large number of domain-like bend striations in the order of several tens of angstrom units wide, indicating a typical relaxor domain structure. Similar domain striations were previously reported by Xu et al. [ 25 ] in the compositions near the MPB of PMN- x PT and were designated as tweed-like ...
