Abstract:
An electric circuit comprising:a composite structure (10) having at least one layer of ferroelectric material (11), with a first surface and an opposed second surface, and a first semi-conductor, metal film or superconductor material (12) layer in contact with the first surface of the layer of ferroelectric material (11); and a device for generating local modification in a polarization of the layer of ferroelectric material (11) to one of: (1) locally modify an electronic density of a zone of the first semi-conductor, metal film or superconductor material (12), the zone being near the first surface of the layer of ferroelectric material (11), or (2) create a local deformation in the layer of ferroelectric material (11) to generate an acoustic surface wave; the device for generating the local modification in the polarization of the ferroelectric material (11) comprises at least one selective electrode for selectively scanning a second surface of the composite structure (10) and applying at least one of a voltage and a current between the electrode and the semi-conductor, metal film or superconductor material.
