Active spatial control of photothermal heating and thermo-actuated convective flow by engineering a plasmonic metasurface with heterodimer lattices
文献摘要：
Thermo-plasmonics,using plasmonic structures as heat sources,has been widely used in biomedical and micro-fluidic applications.However,a metasurface with single-element unit cells,considered as the sole heat source in a unit cell,functions at a fixed wavelength and has limited control over the thermo-plasmonically induced hydro-dynamic effects.Plasmonic metasurfaces with metal disk heterodimer lattices can be viewed to possess two heat sources within a unit cell and are therefore designed to photo-actively control thermal distributions and fluid dynamics at the nanoscale.The locations of heat sources can be switched,and the direction of the convective flow in the central region of the unit cell can be reversed by shifting the wavelength of the excitation source without any change in the excitation direction or physical actuation of the structural elements.The temperature and velocity of a fluid are spatiotemporally controlled by the wavelength selectivity and polarization sensitivity of the plasmonic metasurface.Additionally,we investigate the effects of geometric parameters on the surface lattice resonances and their impact on the temperature and fluid velocity of the optofluidic system.Our results demonstrate excellent optical control of these plasmonic metasurface heating and thermal convection performances to design flexible platforms for microfluidics.
