Characterization of GO and laser scribed rGO. Morphology comparison of (a) SEM images depicting the difference between the surface structure of GO and rGO. (b) The porous structure of rGO after reduction. (c) rGO flakes sharing their surface area with each other helps in sensing strain. (d) The thickness of rGO increases with respect to GO after reduction. (e) RAMAN spectroscopy of GO and rGO depicts that the reduction has taken place. (f) A sharp peak of XRD Diffraction at 10.75° confirms GO and after the reduction, another peak at 22.1° confirms rGO structure.
