abstract = "Novel nanotextured Au surfaces are presented with periodically self-aligned nanopyramid structures with precisely defined pitch that are closely packed with 2 nm separation gaps over large areas and form high-density (similar to 1 km cm(-2)) arrays of hot-spot scattering sites ideally suited for surface-enhanced Raman scattering (SERS) and Raman spectroscopy. Average Raman enhancement factors from physically adsorbed rhodamine 6G on patterned Au surfaces resulted in EF similar to 10(6). The Raman average EF has been characterized over large areas using benzenethiol monolayers chemisorbed on the Au nanopyramid surfaces. From the 1074 cm(-1) ring mode of BT on surfaces with 200 nm pitch the EF=(0.8 +/- 0.04)x10(6), and for surfaces with 500 nm pitch the EF=(0.32 +/- 0.01)x10(7) from over 99% of the imaged area. Maximum EF>10(8) have been measured in both cases",
