Abstract
A layered solid element includes a ferroelectric layer of a crystalline material Li(NbTa)Owhich has X- or 33°Y-orientation with respect to a substrate of the layered solid element. The ferroelectric layer is grown epitaxially from a buffer layer having of one of the chemical formulae LNiOor LNiO, where L is a lanthanide element. Such layered solid element may form a thin-film bulk acoustic resonator and be useful for integrated electronic circuits such as RF-filters, or guided optical devices such as integrated optical modulators.
