Abstract: The electrical, magnetic and optical properties of edge channels consisting of spin circuits that contain single carriers in nanostructures of silicon, silicon carbide and cadmium fluoride are investigated. It is demonstrated that due to the presence of chains of negative-U dipole centers at the boundaries of the spin circuits, the latter are Andreev molecules for generating terahertz radiation.

Keywords: silicon nanosandwich, silicon carbide, cadmium fluoride, terahertz irradiation, current-voltage characteristic, multiple Andreev reflection, Andreev molecule.
