| 中文摘要 | We present a tunneling study of the superconducting gap and pseudogap from near optimally doped submicron Bi2Sr2-xLaxCuO6+delta intrinsic Josephson junctions whose self-heating is significantly suppressed. We find that as temperature decreases a pseudogap develops around T-star = 165 K while the superconducting gap starts to open at T-c0 = 40 K, which is well above the superconducting transition temperature T-c of 30 K. We discuss the temperature-dependent properties of the superconducting phase and pseudogap phase. Our results demonstrate a clear two-gap feature of the system with precursor pairing up to T-c0. |
