TEM images. (a) Cross-section of the H20Hz heterostructure in which PZT layer was first deposited at 5 Hz repetition frequency (region 1 with dense packing) and then 20 Hz repetition frequency (region 2 with separated columns). (b) A magnified image of Ca2Nb3O10 nanosheet and glass interface. (c) A magnified image of the columns from region 2 of the PZT film. (d) Selected area electron diffraction pattern recorded for one of the column confirming an epitaxial growth.
