| 中文摘要 | Temperature, T and doping dependent tunneling spectroscopy on Bi2Sr2CaCu2O8+delta/natural barrier/Zn thin film (Bi2212/I/Zn) junctions has been investigated systematically. For most of the junctions, the tunneling conductance shows one superconducting gap (SG) at low T and a discontinuous transformation from the SG to the pseudogap (PG) at T-c For some junctions studied, the conductance reveal two distinct gaps: an inner gap which closes when T approaches to T-c with BCS-like T-dependence, and an outer gap, coexisting with the inner gap for T below T-c, which is almost T-independent below about 120 K. We discuss the possible origins of the coexistence of the two gaps, including the coexistence of the SG and PG and the gaps resulting from electronic or doping inhomogeneity.
