Characterization of Ag/Bi{sub 2}Sr{sub 2}Ca{sub n-1}O{sub 2n+4} interfacial resistivity.
Silver contacts to single-crystal Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub x} (Bi-2212) and polycrystalline (Bi,Pb){sub 2}Sr{sub 2}Ca{sub 2}Cu{sub 3}O{sub x} (B-2223) were prepared by sputtering or sinter-forging techniques. The interfacial resistivity of Ag/Bi-2212, defined as interfacial resistance times contact area, decreased from 10{sup -4} to 10{sup -10} {Omega} cm{sup 2} at 77 K when the thermal annealing time increased from 1 to 14 h at 600 C; it was also a function of the annealing temperature. The lowest interfacial resistivity of Ag/Bi-2223 that was sinter-forged at 840-845 C for 1 h was 10{sup -9} {Omega} cm{sup 2} at 77 K. Experimental data are compared with intrinsic interfacial resistivity and resistivity values found in the literature.
