Visualization of three dimensional domain structures in ferroelectric PbTiO3 nanotubes
2013
Applied Physics Letters
We report visualization of three-dimensional domain structures in ferroelectric PbTiO 3 (PTO) nanotubes (NTs) using piezoresponse force microscopy (PFM). The domain distributions of the x, y, and z-axes in PTO NTs were separately measured out-of and in-planes at angles of 0 and 90 by vertical and lateral PFM. The separately obtained PFM images were combined to reconstruct the complex domain structures based on some basic assumptions and finite element modeling. The cross-sectional domain
