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 (∼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∼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 -1ring mode of BT on surfaces with 200 nm pitch the EF=(0.8±0.04)×10 6, and for surfaces with 500 nm pitch the EF=(0.32±0.01) ×10 7 from over 99\% of the imaged area. Maximum EF>10 8 have been measured in both cases.",
