Özet
İngilizce (OpenAlex)
Point contact tunneling data are reported in a multilayered high-T c cuprate (Cu,C)Ba 2 Ca 3 Cu 4 O 12+δ with T c = 117 K . The tunneling spectra in the superconducting state (T ≪ T c ) display spectral features such as well-defined superconducting gap peak at ±Δ as well as dip-hump structures beyond the peaks. In some cases, the spectra with two-gaps have been observed, indicating the coexistence of two inequivalent superconducting layers. The statistical distribution of superconducting gap magnitude suggests two distinct kinds of superconducting gaps that may originate from two inequivalent CuO 2 planes, a characteristics of multilayered cuprates with n ≥ 3.
