▲ [14p-C302-9] All-dielectric Nanoantenna Sensors
キーワード:sensor, dielectric, nanostructure
All-dielectric nanostructures having both electric and magnetic resonance that could be used in near-fields optics, surface enhanced Raman spectrometers (SERS), or sensor applications. Optical sensor criteria, like narrower full-width half maximum (FWHM), and larger figure of merit (FOM) are important. However, the FWHM in plasmon resonance of metal nanostructures could not be very small because of the intrinsic loss of metal.
In this study, it is observed that the FWHM of silicon nanoantennas (Si NAs) is narrower than gold nanoantennas (Au NAs). Combining with the advantage in low cost and CMOS compatible process, silicon nanoantenna could be a good candidate in bio-sensing application.
