Essay

The dissertation is devoted to studying mechanisms of the electron transport in multi-barrier and asymmetric tunnel junctions. New aspects of Josephson tunneling were found for multiple (SIS)n junctions with n=2 and n>2, where S is a superconductor and I is an insulator. It is established that SINIS-type junctions (here N is a thin, of order of the coherence length, layer of a normal metal, or a superconductor with the energy gap being reduced as compared with that for S) constitute a new class of Josephson junctions, in which coherent tunneling is possible both at zero and finite voltage. New devices have been proposed as promising for cryoelectronics applications.
