文摘

Preparation and spectroscopic studies on carbonaceous materials were performed. Drude-Lorentz model were used for fitting the optical conductivity spectra. The plasmonic resonances have been observed in THz frequency range. The charge density N has been effected by disordered of the grapheme structure. The σDC values is decreased in case of 2D carbonaceous materials.
