摘要：
Using Zn thin film as counterelectrode, Bi2Sr2CaCu2O8+delta tunnel junctions were prepared. Temperature-dependent tunneling spectra of these planar junctions provided measurements of energy gap, 2 Delta, and transition temperature, T-c. The spectra also allowed the observation of pseudogap in normal state and showed strong evidence of d-wave symmetry of the superconducting order parameter. The present junction may find its way in the electronics applications. (C) 2000 American Institute of Physics. [S0003-6951(00)02023-4].
