Abstract
We present dc resistivity multi-terminal measurements performed in Bi2Sr2CaCu2O8+delta single crystal. Sample doping was varied from underdoped to slightly overdoped. Data are analyzed in term of a model which assumes two different mechanisms for the out-of-plane conduction, markedly thermal activation and incoherent tunneling. Within this model we are able to describe data of normal state resistivity. We also analyze data from the literature. In all cases, the proposed model describes very well the data in the normal state. (C) 2003 Elsevier Science B.V.
