Intrinsic tunneling spectra of Bi_2(Sr_{2-x}La_x)CuO_6 [PDF]
, 2002 We have measured intrinsic-tunneling spectra of a single CuO-layer La-doped Bi_2Sr_{2-x}La_xCuO_{6+\delta} (Bi2201-La_x). Despite a difference of a factor of three in the optimal superconducting critical temperatures for Bi2201-La_{0.4} and Bi2212 (32 ...
