Tunnel characteristics of intrinsic Josephson junctions in (Bi{sub 1{minus}x}Pb{sub x}){sub 2}Sr{sub 2}CaCu{sub 2}O{sub y} single crystals

Journal Article · · International Journal of Modern Physics B
The authors have studied the current-voltage characteristics of intrinsic Josephson junctions in mesa-shaped Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub y} and (Bi{sub 1{minus}x}Pb{sub x}){sub 2}Sr{sub 2}CaCu{sub 2}O{sub y} single crystals as a function of x. Pronounced Josephson tunneling characteristics, which are characterized by high critical current densities and multiple quasiparticle branches with clear subgap structures, have been observed for (Bi{sub {approximately}0.8}Pb{sub {approximately}0.2}){sub 2}Sr{sub 2}CaCu{sub 2}O{sub y}. A strong correlation between the characteristics and structural modulation in this system has been found.
