| Popis: | International audience; We present computer simulations of the work of an electronic device for generation of electric oscillation by negative differential conductivity of a superconductor supercooled below the critical temperature. The superconductor is cooled below its critical temperature in the normal state at a small constant electric voltage. To simulate the device, we use formerly derived explicit analytical expressions for the conductivity of nanostructured superconductors supercooled below the critical temperature in an electric field. Computer simulations reveal that the negative differential conductivity region of the current–voltage characteristic leads to excitation of electric oscillations. We simulate a circuit with distributed elements as a first step to obtain gigahertz frequency. This gives a hint that a hybrid device of nanostructured superconductors will work in terahertz frequencies. If the projected setup is successful, we consider the possibility for it to be put in a nanosatellite (such as a CubeSat). The study of layered high-T c superconductors and EM waves emitted from them in space vacuum would be an important task for future space technology. |
