Abstract
A structure for radiofrequency applications includes a high-resistivity support substrate having a front face defining a main plane, a charge-trapping layer disposed on the front face of the support substrate, a first dielectric layer disposed on the charge-trapping layer, an active layer disposed on the first dielectric layer, at least one buried electrode disposed above or in the charge-trapping layer. The buried electrode comprises a conductive layer and a second dielectric layer.
