Raman spectroscopy data. Peaks position ( D, G), graphite peak (G), defect disorder peak (D), the degree of graphitization using the ratio of the integrated area intensity of graphite, and the intensity area of defect disorder peak (ID/IG). Sheet resistance (R) and conductivity (σ) of the activated films on the glass substrates.
