ABSTRACT
We theoretically investigated the plasmon interferences and hybridization in the Au–Ag nanorod heterodimers. Twinned Fanolike profiles are observed in the absorption cross sections of the gold and silver nanorods in the heterodimers, the Fano factors of which have the opposite signs near the antibonding resonances, which are found to be induced by the destructive interferences of two hybridized local surface plasmons. Both the value and sign of the Fano factors could be tuned by adjusting rod-lengths, which could find the applications in the design of plasmonic nanodevices.
