Implications of tunneling studies on high-Tc cuprates: Superconducting gap and pseudogap
Tunneling spectra have been measured on high-Tc cuprates including single crystals Bi2Sr2-xLaxCuO6+δ (Bi2201) and Bi2Sr2CaCu2O8+δ (Bi2212) using superconductor-insulator-normal metal point contact or superconductor-insul ...
Superconducting gap and pseudogap from tunneling conductance on Bi2Sr2CaCu2Og+δ with various oxygen concentration
The evolution of tunneling spectra on Bi2Sr2CaCu2Og+δ measured by SIN point contacts, SIS break junctions and STM/STS has been studied as a function of doping and temperature. The detailed examinations of the spectra show ...
Tunneling studies of multilayered superconducting cuprate (Cu,C)Ba 2Ca3Cu4O12+δ
(World Scientific Publishing, 2003-08)
Point contact tunneling data are reported in a multilayered high-T c cuprate (Cu,C)Ba2Ca3Cu4O 12+δ with Tc = 117 K. The tunneling spectra in the superconducting state (T ≪ Tc) display spectral features such as well-defined ...
