FIG. 1.

A schematic diagram of the SAW device with PITs (piezoelectric IDTs). The PITs are made of ferroelectric domains with alternating polarization states written in the -axis oriented PZT films. (b) Schematic representation of the domain deformation with applied rf voltage. The deformation (elongation or contraction) for a given voltage depends on the polarization direction.

FIG. 2.

Piezoelectric microscopy image of one of the prototype SAW devices.The distance between the input and output PIT is around and that between two adjacent line-shaped domains of opposite polarization is , leading to a wavelength. (b) Line section through piezoresponse (PR) image of one of the PITs.

FIG. 3.

Reflection spectra of (dotted line) and (solid line) wavelength devices with PITs.
