Abstract

The current voltage characteristics of intrinsic Josephson junctions in thin films of Tl2Ba2Ca2Cu3O10+δ and Bi2Sr2CaCu2O8+δ single crystals show pronounced subgap structures at voltages well below the gap. These voltages are independent of sample geometry, magnetic field and temperature up to 0.5 Tc. We discuss possible explanations and show that the structures could be explained by a peak in the quasiparticle contribution to the total current. For superconducting superlattices a subgap peak in the quasiparticle density of states has been predicted theoretically and could explaine our results.
