Caption

a, Schematic of grating processing of a GO film using cylindrical focusing of femtosecond laser pulses. The sample (GO/SiO2/Si) is mounted on a three-dimensional translation stage. The cyan and red arrows represent the directions of the sample scanning (S) and the linear polarization (E) of the laser, respectively. b, Photograph (insert) and SEM image of the large-area (10×12 mm2) rGO-LIPSS. The uniform structural colour shows the spatially regular distribution of structures, where θ represents the angle between S and E. It can be precisely adjusted by a half-wave plate and a Glan-Taylor prism.
