This paper presents a self‐assembly method for fabrication of regular ordered gold metallic structures, and a study of the local field intensification phenomena in the surface of such structures by the enhanced Raman scattering spectra of the crystal violet molecules adsorbed on the surfaces of these structures. The enhanced phenomena were attributed to the local field intensification at the metallic surface due to surface plasmon modes in the interconnected nano‐sized gold structure within the regular array structures.
