Tunneling spectroscopy of Tl2Ba2CaCu2O8 single crystals and thin films

Daniel Mazur, J. F. Zasadzinski, K. E. Gray +3

Early electron tunneling experiments with the Tl2Ba2CaCu2O8 measured Δ= 16-28 meV, while bulk optical experiments measured Δ= 43-45 meV. We report new tunneling measurements of Tl2…
