Abstract (en)

[origin: WO2008145864A2] The invention relates to a device for information mass storage that comprises: a substrate (30); an electrically conducting tip for atomic-force microscopy (10) provided above the surface (31) of the substrate (30) and in electric contact with the latter; and a voltage generator (41) for applying a potential difference between said tip (10) and said substrate (30). The device is characterised in that the substrate (30) includes a surface (31) made of a material having an electric conductivity both of the electronic and ionic type, and in that said generator (41) is adapted for applying a potential difference sufficiently high for triggering an oxidation-reduction reaction of said material, thus modifying the electric conductivity of the surface of the substrate (30). The device (1) can be used for information mass storage.
