Evidence for strong electron-phonon interaction from inelastic tunneling of Cooper pairs in c-direction in Bi sub(2)Sr sub(2)CaCu sub(2)O sub(8) break junctions

A reproducible fine structure at subgap voltages in the I(U)-characteristics of Bi sub(2)Sr sub(2)CaCu sub(2)O sub(8) break junctions has been observed and investigated. The structure is detectable only in the presence of an a.c. Josephson current. The position of the dips, composing the structure i...
