Abstract

The inexpensive fabrication method of self organized metal nanostructures with adhesion layer over large area is proposed. The method combines dry etching using a self-organized mask to prepare a template and directional metal deposition on the elevated part of the obtained template. The technique peculiarities were studied during fabrication of metal lace-like nanostructures prepared with Ti layer and without it. The results demonstrate the overall difference in transmittance and reflectance spectra of the samples due to presence of Ti layer. Surface enhanced Raman spectroscopy (SERS) experiments were performed with methylene blue and confirmed decreasing of SERS intensity of the gold nanostructures with adhesion layer. The obtained results can be used in fabrication of self-organized metal nanostructures with controllable adhesion.
