(a) Composited and EDPs from a cross-sectional TEM sample and (b) a schematic showing threefold symmetric and variants with opposite directions.
(a) A typical bright-field TEM image of the LTO thin films on sapphire; (b) an enlarged image from (a); (c) the corresponding EDPs of (b); and [(d) and (e)] dark-field image by using and (as inserted), respectively.
A Fourier-filtered HREM image corresponding to the domain boundaries between and variants in Fig. 2. The directions of are marked by big white arrow-heads. A structural model corresponding to the domain boundary between and variants is inserted.
Four kinds of possible domain configurations between variants and . [(a) and (b)] having the opposite directions; [(c) and (d)] with the same directions. Type II in (b) has more possibilities than type I in (a) in the ferroelectric LTO; and [(c) and (d)] are unreasonable.
