Disclosed is a complementary resistor switch ( 3 ) comprising two outer contacts, between which two piezo- or ferroelectric layers ( 11 a and 11 b ) 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. |
