We investigated nanoscale surface modifications of silicate glass plates by applying a thermal nanoimprint technique, in which self-organized nanopattern molds of sapphire (α-Al 2 O 3 single crystal) wafer were used. Nanopatterns of the sapphire mold exhibited regularly arranged straight atomic-steps with a uniform height of 0.2nm and atomically flat terraces about 80nm in width. We...
