Analysis of the pseudogap-related structure in tunnel spectra of the superconducting Bi₂Sr₂CaCu₂O₈₊δ revealed by break-junction technique
Tunnel conductance G(V)for break-junctions made of as-grown single-crystal Bi₂Sr₂CaCu₂O₈₊δ samples with Tc≈86-89 K was measured and clear-cut dip-hump structures (DHSs) were found in the range 80-120mV of the bias voltage V. The theory of tunneling in symmetric junctions between inhomogeneous cha...

| description |
Tunnel conductance G(V)for break-junctions made of as-grown single-crystal Bi₂Sr₂CaCu₂O₈₊δ samples
with Tc≈86-89 K was measured and clear-cut dip-hump structures (DHSs) were found in the range
80-120mV of the bias voltage V. The theory of tunneling in symmetric junctions between inhomogeneous
charge-density-wave (CDW) superconductors, considered in the framework of the s-pairing model, has been
developed. CDWs have been shown to be responsible for the appearance of the DHS in the tunnel current-
voltage characteristics and properly describes experimental results.
