利用扫描透射电子显微镜（STEM）中的暗场光学显微镜和电子能量损失谱（EELS）研究了单个银纳米立方体的局域表面等离子体共振（LSPR）之间的Fano干涉现象。通过计算由电子束引起的极化，我们表明，负责这种Fano干涉的混合模式是相同的，存在于基板上的单个纳米立方体的共振瑞利散射光谱。
The Fano interference phenomenon between localized surface plasmon resonances (LSPRs) of individual silver nanocubes is investigated using dark-field optical microscopy and electron-energy loss spectroscopy (EELS) in a scanning transmission electron microscope (STEM). By computing the polarization induced by the electron beam, we show that the hybridized modes responsible for this Fano interference are the same as those present in the resonance-Rayleigh scattering spectrum of an individual nanocube on a substrate.
