We made mm-range closely packed monolayer by using the water/oil interface with Au nanoparticles whose nominal sizes are about 32 nm. We transfer this monolayer to the hydrophilic Si substrates by pulling up the sample softly and we measure the surface enhanced Raman scattering of Rhodamine 6G dye molecules. For this structure, we simulate the electromagnetic field enhancement when the laser light shines the sample whose unit cell is hexagonal structures ideally. We suggest that the strong field enhancement comes from the every interstitial gap among nanoparticles.
