The current-voltage characteristics (IVC) of intrinsic Josephson junctions (IJJ) in c-axis-oriented La2-xSrxCuO4 (LSCO) thin films were demonstrated. The large intrinsic junctions (LIJ) with a mesa structure exhibited resistively shunted junction (RSJ)-like IVCs. The results indicated that the IJJs in the LSCO thin films are characterized as stacked SIS Josephson junctions and that the grain boundaries act as shunting resistance.
