| dc.description.abstract | We explore the effects of crystallite size (La) on the linear and non-linear optical properties of chemical vapor deposition grown polycrystalline graphene. The π-plasmon resonance present at [similar]4.75 eV ([similar]260 nm) in the optical absorption spectrum of graphene follows the empirical relationship λπ = 250.5 nm + 89.5 nm2/La, where λπ represents the π-plasmon wavelength. Furthermore, our Z-scan studies reveal that the crystallite size significantly changes the saturation intensity in CVD grown graphene. Notably, in comparison to epitaxial graphene layers grown on SiC wafers which exhibit a photogenerated carrier lifetime of few picoseconds, we find that the photogenerated carriers in our CVD grown graphene can exhibit lifetimes as long as nanoseconds. | en |
