Disclosed is a complementary resistor switch () comprising two outer contacts, between which two piezo- or ferroelectric layers (and) having an inner common contact are situated. At least one region (&#x2033;) of the layers is modified, either the outer contacts are rectifying (S) and the inner contact is non-rectifying (), 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.
