Oscillatory behavior in the electrical resistivity of transition-metal superlattices

The electrical resistivity of Co/Ni and Cu/Ni superlattices exhibit resistivity oscillations as a function of superlattice periodL, while Ag/Pd does not. Moreover, the resistivity of Co/Ni superlattices shows quantum size effects and a resistivity enhancement with L, as a function of total film thickness d. These results are consistent with a model which… CONTINUE READING
