  • Publication number: 20120211368
    Abstract: The invention relates to a method for producing a switch element. The invention is characterized in that the switch element comprises three electrodes that are located in an electrolyte, two of which (source electrode and drain electrode) are interconnected by a bridge consisting of one or more atoms that can be reversibly opened and closed. The opening and closing of said contact between the source and drain electrodes can be controlled by the potential that is applied to the third electrode (gate electrode). The switch element is produced by the repeated application of potential cycles between the gate electrode and the source or drain electrode. The potential is increased and reduced during the potential cycles until the conductance between the source and drain electrode can be switched back and forth between two conductances, as a result of said change in potential in the gate electrode, as a reproducible function of the voltage of the gate electrode.

  • Publication number: 20030155246
    Abstract: The present invention relates to a method for producing surface-structured substrates, wherein a predetermined defined surface structuring is transferred to the surface of a substrate by activating the substrate surface using at least one fine probe that interacts with the substrate surface, and material of a liquid, solid, or molten salt electrolyte is electrochemically deposited in a selective manner on the regions of the substrate surface that are activated thereby. The invention also relates to a device for surface structuring of substrates.
