Abstract
The disclosure relates to a hybrid structure for a surface-acoustic-wave device comprising a useful layer of piezoelectric material joined to a carrier substrate having a thermal expansion coefficient lower than that of the useful layer; the hybrid structure comprising an intermediate layer located between the useful layer and the carrier substrate, the intermediate layer being a structured layer formed from at least two different materials comprising a plurality of periodic motifs in the plane of the intermediate layer.
