Imprinted structure and the results of the AFM and SNOM characterization of the imprinted GMN. (a) Scheme of the stamp and the sample surface after the EFI process. The stamp grooves of 100, 150, 200, 250, 300, 350, 400, 450, 500, and 600 nm in width and corresponding imprinted strips are marked with numbers from 1 to 10, respectively. (b) AFM of the composite sample surface after the EFI process. Quantitative data is presented in the next figures. Near-field images of the sample at three different excitation wavelengths: (c) 633, (d) 532, and (e) 405 nm.
