(a) Micro-Raman spectra of N100 sample fitted to Lorentzian function; and peaks are located near ~1350 and ~1600 cm1. (b) This graph shows comparison between ratios for each sample. By using only helium (N0), the number of defects is always higher than samples that were obtained by using nitrogen and/or its mixture with helium.
