“…Mazurkiewicz and coworkers suggested that the pits were due to the imperfections on the template surface during evaporative deposition. [43] Our results on silicon are not supportive of this mechanism. Figure 3(f) is an AFM image of the template after stripping off the nonannealed gold layer.…”

High-quality atomically flat substrates are critical for the analysis and imaging of surface-mounted ultrathin films and nanostructures. Here we report significant improvement in the preparation of large areas of atomically smooth Au(111) substrates. A thin layer of gold on silicon is flame-annealed in air and then stripped from the template. The substrates were analyzed with X-ray diffraction and high-resolution atomic force microscopy (AFM). In contrast to the previously reported template stripped gold (TSG) substrates, flame-annealed template stripped substrates reveal no detectable pinholes. The substrate surface is atomically smooth with most grains being larger than 1 µm 2 . The entire procedure requires less than 2 h and uses readily available materials and common laboratory equipment. The resulting substrates can be stored for longer periods of time and then used immediately without need for common cleaning procedures. Evidence is provided that self-assembled monolayers on these substrates are higher quality than those prepared with previously reported gold substrates.

“…Large atomically-flat gold substrates were stripped from the mica template using procedure described by Shapter [25]. The basic idea is to use the first gold atomic layer which has been deposited directly on the mica rather than the top gold surface.…”

“…This feature raises the exciting possibility of one monolayer forming system being suitable for a large range of electrode materials for a diverse range of applications. Gold is important relative to carbon as it has a lower capacitance, and it can be produced very flat [35,36] or as a single crystal, and is compatible with microfabrication technologies.…”
