Abstract: Disclosed is a complementary resistor switch (3) comprising two outer contacts, between which two piezo- or ferroelectric layers (11a and 11b) having an inner common contact are situated. At least one region (11′, 11″) of the layers is modified, either the outer contacts are rectifying (S) and the inner contact is non-rectifying (0), or vice versa, the modified regions are formed at the rectifying contacts, the layers have different strain-dependent structural phases with different band gaps and/or different polarization charges, and the electrical conductivity of the layers is different. Also disclosed are a connectable resistor structure having at least one Schottky contact at two adjoining piezo- or ferroelectric layers, a polycrystalline piezo- or ferroelectric layer comprising modified crystallites, and a method and circuits for encrypting and decrypting a bit sequence.

Abstract: A method for reconfiguration of a vortex density in a rare earth manganate, to a non-volatile impedance switch having reconfigurable impedance, and to the use thereof as micro-inductance is disclosed. A unique voltage-time profile is applied between a first and a second electrically conductive contact attached to the rare earth manganate, such that the rare earth manganate passes through an ordering temperature in a region of an electric field forming between the two electrically conductive contacts during a cooling process during and after application of the voltage pulse or the voltage ramp, and the vortex density is thus influenced and adjusted locally in the region of the electric field forming between the two electrically conductive contacts.

Abstract: A transparent specimen slide on which the range and the magnitude of the near-surface electrostatic forces can be influenced and set during a process of producing the specimen slide. The specimen slide has a surface on the supporting side and a surface facing away from the supporting side and at least three layers: an electrically insulating first layer, a silicon-containing second layer arranged on the first layer, and an electrically insulating third layer arranged on the second layer. An interface is formed between the first and second layers and between the second and third layers with a first surface charge density. The interface between the second and third layers has a second surface charge density. The first and second surface charge densities have the same or different signs.
