Well-defined Fano effect in the Andreev reflection process of a parallel double-quantum-dot structure

et al.

Abstract: We investigate the Andreev reflection in the parallel double-quantum-dot structure, by considering one metallic lead and one s-wave superconductor to couple to the quantum dots simultaneously. It is found that the Fano lineshhape has opportunities to appear in the linear conductance spectrum of the Andreev reflection, which can be reversed by tuning the dot level or local magnetic flux. However, the property of the Fano effect is very complicated, in comparison with the normal electron tunnelling case. This is… Show more
