Abstract The measurements of anisotropic resistivities of single- and double-layered Bi-system cuprates at different doping levels are presented. The two types of materials exhibit qualitatively common features in both doping and temperature dependences of their c-axis resistivities. The c-axis conduction is incoherent in nature because the ϱc data are deeply on the insulating side of the Mott limit, even though positive slopes (dϱc/dT〉0) are observed below room temperature for overdoped samples. Some differences are revealed by quantifying the trend of ϱc(T) data, which may reflect differences in the charge excitation spectra.
