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 (Bi-2212) whiskers by changing the carrier density with an annealing process. As a result, the Jc decreased, and the RN increased…
