Abstract ： We report temperature-dependent behavior of the zero bias tunneling conductance (ZBTC), derived from tunneling spectroscopies on as-grown Bi2 Sr2 CaCu2 O8+δ (Bi2212) single crystals taken with evaporated Zn and Pb planar junctions. At Tc the measured ZBTC shows a kink which gives an in situ measure of the superconducting transition temperature (Tc ). Below Tc , the T2 dependence of the ZBTC has been observed repeatedly as a new evidence of the d-wave symmetry in Bi2212.
