Metal/Semiconductor hybrid nanostructure is promising for its unique opt-electrical performance enhanced by surface plasmon resonance(SPR).However,the noble metals(Au,Ag,etc.)usually used for plasmonic are not cost-effective.In contrast,Bismuth is a cheap but promising metal with high plasmon-excitation efficiency comparable with Au.Here,the high crystalline Bi-nanorod/Si-nanodot hybrid structure is prepared by alternated sputtering of Bi and Si.FDTD simulation shows that the Bi-nanorod/Si-nanodot hybrid structure possesses red-shifted SPR ...
