Abstract
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 (″) of the layers is modified, either the outer contacts are rectifying (S) and the inner contact is non-rectifying (O), 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.
