Figure2 | Photoelectric response of the rGO samples with the rGO-LIPSS.

Caption

a, Schematic diagram (left) and photographs (right) of the angle-resolved photoelectric measurement of rGO samples. The top-down materials of the samples are gold electrodes, rGO-LIPSS, SiO2 film and Si substrate. α represents the angle between the alignment of the electrode pair used for measurement (the green arrow) and the reference position (the red arrow). The scale bars are 20 μm (top) and 5 μm (bottom). b, c, Light absorption and corresponding infrared images at the positions of the GO film and the rGO-LIPSS. The scale bars are 500 μm. d, α-dependent I-V curves (main) and conductance (inset) of rGO samples. e, Photoresponsivity and photocurrent of rGO samples under irradiation by LED white light (OPTO SIGMA, SLA-100). f, Temporal photoresponse of rGO samples under 1 mW irradiation.
