We propose a simple model which accounts for the major features and systematics of experiments on the {ital c}=axis resistivity, {rho}{sub {ital c}} for La{sub 2{minus}{ital x}}Sr{sub {ital x}}CuO{sub 4}, YBa{sub 2}Cu{sub 3}O{sub 6+{ital x}}, and Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8}. We argue that the {ital c}-axis resistivity can be separated into contributions from in-plane dephasing and the {ital c}-axis {open_quote}{open_quote}barrier{close_quote}{close_quote} scattering processes, with the low-temperature semiconductorlike behavior of {rho}{sub {ital c}} arising from the suppression of the in-plane density of states measured by in-plane magnetic Knight shift experiments. We report on predictions for {rho}{sub {ital c}} in impurity-doped YBa{sub 2}Cu{sub 3}O{sub 6+{ital x}} materials. {copyright} {ital 1996 The American Physical Society.}
