The control of the critical current density (Jc) and the junction resistance (RN) along the c-axis of intrinsic Josephson junctions (IJJs) on a high-Tc superconductor is very important for applying the IJJs to electronic devices. For controlling these junction parameters, we have clarified the relationship of Jc, RN and the carrier density in Bi2Sr2CaCu2O8+δ whiskers by changing the carrier density with an annealing process. We determined the electrical transport characteristics of the IJJs. As a result, the Jc increased, and the RN decreased systematically when the carrier density increased. The values of Jc and RN could be controlled by a change in the carrier density.
