Abstract
The current-voltage characteristics and dI(V)/dV characteristics of tu nnel break junctions in single-crystal Bi-Sr-Ca-Cu-O:Pb samples (the 2 212 phase) have been studied at a temperature of 4.2 K. The I-V curve has regions with a negative resistance at bias voltages V in the inter vals 2-4 mV and 38-40 mV. These regions are linked with features in th e density of states which stem from the layered structure of this high -T(c) superconductor.
