    Patent number: 6677629
    Abstract: The invention concerns a component of composite structure (10) consisting of a layer of ferroelectric material (11) and at least a thin film of semiconductor material or of a thin metal or supraconducting film (12) in close contact with the layer of ferroelectric material (11). It further comprises means for generating local modifications of the ferroelectric material polarization. This mechanism includes a device for applying a voltage between at least one punctiform electrode (13) arranged for selectively scanning the composite structure (10) surface facing that consisting of the semiconductor or thin metal or supraconducting film (12), and the semiconductor or thin metal or supraconducting film.
