Gold nanoparticles decorated silicon nanowires thin-film absorbers
首发时间:2017-05-02
Abstract:We proposed a thin-film absorber based on gold nanoparticles decorated silicon nanowires on thin gold film, with which broadband and enhanced absorption was experimentally demonstrated compared with others without gold nanoparticles or gold film. The high absorption was attributed to not only the top gold nanoparticles, which introduced enhanced light coupling and reduced reflection due to the exciation of surface plasmon polaritons, but also the bottom gold thin film, which greatly suppressed the light transmission.
