Lab. and Univ. of, Illinois/Chicago, Chicago, IL, USAUnited States, 1996)
      Using high resolution angle-resolved photoemission spectroscopy (ARPES), we measure the superconducting gap and its momentum dependence in the high temperature superconductors Bi 2Sr 2CaCu 2O 8 (Bi2212) and YBa 2Cu 3O 6.95 ...

      Tunneling in Pb-YBCO junctions: Determining the symmetry of the pairing state 

      Wollman, D. A.; Harlingen, D. J. Van; Giapintzakis, John; Ginsberg, D. M. (1995)
      We report on our efforts to understand the origin of supercurrent observed in c-axis tunnel junctions on YBCO [Sun A. G. et al., Phys. Rev. Lett. 72, 2267 (1994).] by studying the phase coherence of a-axis/c-axis and ...
