Abstract


Au nanofins and double nanopillars were fabricated successfully with a wafer-scale through the nanocoating lithography technique. Each structure has own structural feature and shows plasmon resonances depending on its size and shape, resulting in a plasmon sensor. Au double nanopillars showed a high refractive index sensitivity of 1075 nm/refractive index units.
