Fig. 3

a–c Current-sensing AFM imaging of laser-irradiated spots made under different wavelengths and similar optical powers. d–f current-voltage characteristics from individual spots obtained at low (orange) and high (red) laser powers and wavelengths (see I(V) characteristics for all utilized powers in Supplementary Fig. 8). ITO is taken as a reference (blue). g Conductance as a function of optical power and temperature on the spots at different irradiation powers. The inset shows the electrical scheme and measured resistance represented by the sum of contact resistances between wire and ITO, ITO and rGO, and rGO and AFM tip. Temperature values for each laser power were obtained by Raman thermometry. Source data are provided as a Source Data file.
