Fabrication of Plasmonic Nanoplatforms for Single-molecule Detection and Self-Cooling Nearfield Thermal Emission Device

The optical emission characteristics from the nano-apertures on the Au nano-plasmonic platform will be reported. Regardless of the nano-aperture type of either circular type or nanoslit type, the spp-mediated optical emission characteristics dependent upon the sample thickness and aperture size are observed. In addition, the spp mediated optical characteristics are observed to be increasing with decreasing the aperture size and to be independent of the nano-aperture shape due to the spp-mediated intraband emission. We are investigating the characteristics for the fabricated nanometer slit array and circular-type aperture array, and the fabricated plasmonic platfoms can be utilized as various applications such as plasmonic sensors and plasmomic self- cooling due to its broad emission spectra from the visible to the infrared regime.
