论文摘要
预测1950年代由光 - 物质相互作用引起的表面电荷（表面等离子体）的集体振荡会影响2D高贵金属的电传导。主要是两种机制，后来由弗洛希（Frohlich）预测，这可能会影响金属中的电子传输。 （1）由于S波段电子对D波段电子筛选，在过渡金属中的自由电子之间的Umklapp电子散射和（2）自由电子之间的有吸引力的相互作用。 [1] However, there is no experimental evidence to date on how such oscillations might influence the electrical conductivity of 2D metals.我们已经对表面等离子体进行了原位测量和薄膜金的电阻率。我们观察到高贵金属薄膜的电阻率与表面等离子体共振之间的显着相关性
The collective oscillations of surface charges (surface plasmons) induced by light-matter interactions were predicted in the 1950s to influence electrical conduction in 2D noble metals. Primarily two mechanisms were predicted and later by Frohlich which could affect the electron transport in metals; (1) Umklapp electron-electron scattering and (2) attractive interaction between free electrons in transition metals because of screening of the d-band electrons by the s-band electrons. [1] However, there is no experimental evidence to date on how such oscillations might influence the electrical conductivity of 2D metals. We have conducted in-situ measurements of the surface plasmons and electrical resistivity of thin film gold. We observe striking correlations between the electrical resistivity of noble metal thin films and surface plasmon resonance
