Current-voltage characteristics of multilayer tunnel structures with high transmission level of tunnel barrier
Nevirkovets I. P.
The current-voltage characteristics of a double tunnel superconducting structure Sn-I-Sn-I-Pb with a high transmission level of the tunnel barriers have revealed the presence of structural features at the voltages (APb — ASn ) /e, 2ASn /e> and (ASn + APb )/e. These features show that single-particle tunneling through individual junctions has a nonadditive effect on the resultant /^characteristic.
