Abstract
The nonlocal transport properties of the silicene-based Fibonacci and periodic superconducting superlattices with two ferromagnets are investigated and compared. It is found that the Fibonacci superconducting superlattice (FSSL) exhibits larger crossed Andreev reflection (CAR) probability than the periodic superconducting superlattice (PSSL) for normal incidence. The CAR differential conductance shows anomalous behavior with the generation number of Fibonacci structure due to disorder effect. Within the subgap regime, the oscillation of the elastic cotunneling differential conductance for the FSSL is more irregular than that for the PSSL. Moreover, the super-Poissonian noise of the FSSL is suppressed compared with that of the PSSL.
