Figure 7From: Preparation of periodic surface structures on doped poly(methyl metacrylate) films by irradiation with KrF excimer laserAFM images of PMMA-FR samples modified under different angles of laser beam incidence. Laser (50 pulses and 12 mJ cm−2). (A) Non-irradiated. Irradiated at (B) 0°, (C) 20°, (D) 30°, (E) 40°, (F) 50°. Insets give the amplitude scale bars.Back to article page
