氧化铟锡（ITO）薄膜中的表面等离子体共振的观察补充的混合ITO/Au导电层的电荷密度可以调谐的效果。在载流子密度相似（ITO和纳米颗粒Au）的情况下，等离子体行为是单片ITO薄膜的等离子体行为。当一层的载流子密度远大于另一层（ITO和Au金属）时，边界条件导致表面等离子体的抵消。在后一种情况下，观察到足够薄的膜的类电容等离子体共振。(C)2009年美国光学学会
The observation of surface-plasmon resonances in indium tin oxide (ITO) thin films is complemented with the effects of hybrid ITO/Au conducting layers where charge densities can be tuned. Where carrier densities are similar (ITO and nanoparticle Au), the plasmonic behavior is that of a monolithic ITO thin film. Where the carrier density of one layer is much greater than that of the other (ITO and Au metal), boundary conditions lead to cancelation of the surface plasmon. In the latter case a capacitivelike plasmon resonance is observed for sufficiently thin films. (C) 2009 Optical Society of America
