输送的情况下,电子弛豫效应对温度和热应力的影响很大;而在计入这一弹道热输送因素时,电子弛豫效应对薄膜的热应力响应的影响可忽略不计。鉴于实验已明确了薄膜中能量输送的电子弹道运动效应,可以认为,针对脉宽

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.

This paper reports a simple, repeatable approach to fabricate large-area, uniform micro/nanostructures by a femtosecond laser. Specially, 20 nm gold films are coated on semiconductor surfaces on which large-area, uniform micro/nanostructures are fabricated by a femtosecond laser. In the case study of silicon, defects and cross-links are significantly reduced in the laser induced surface structures on Au-coated silicon. The good consistency between the scanning lines facilitates the formation of large-area, uniform surface micro/nanostructures. The diffusion of hot electrons in the Au films increases the interfacial carrier densities, which significantly enhances interfacial electron-phonon coupling. High and uniform electron density suppresses the influence of defects on silicon and further makes the coupling field more uniform and thus reduce the impact of laser energy fluctuations, which homogenizes and stabilizes large-area surface micro/nanostructures. In addition, the proposed new approach might exhibit potential applications, especially in the absorption enhancement of materials surfaces, high surface-enhanced Raman scattering and generation of functional surfaces with hydrophobic wetting behaviors.
